An entire species being colonized without consent by another species that had always been here
In a public square in Vallecas, Madrid, where families had gathered on a Saturday afternoon for the quiet pleasures of a neighborhood book fair, the municipal government inadvertently offered something far stranger: a platform for a man who believes vaccines carry alien microchips. The episode raises an old and unresolved question about the responsibilities of public institutions when the marketplace of ideas admits sellers of something other than ideas.
- A conspiracy theorist with a shuttered YouTube channel and a history of anti-vaccine organizing was given a microphone at a family book fair funded by Madrid's municipal government.
- Attendees expecting poetry and puppet shows instead heard claims that an alien species has been colonizing humanity through graphene-laced vaccines and 5G implants — and some filmed it in disbelief.
- The booksellers of Vallecas, not waiting for politicians, filed a formal complaint, signaling that the disruption to the event's credibility felt personal and immediate.
- Opposition councilor Félix López Rey condemned the programming as intolerable, demanding accountability for how pseudoscientific content reached prime time at a public cultural event.
On a Saturday afternoon in Vallecas, families arrived at the annual book fair along Peña Gorbea boulevard with ice cream in hand, expecting poetry readings and neighborhood history. What they found instead was Ricardo Delgado at the microphone, telling roughly a hundred people that an alien species has been implanting humanity with microchips through vaccines — microchips carrying what he called stellar microwaves, carbon nanotubes, and graphene.
Delgado built his case around the work of Roger Krevin Leir, an American podiatrist who died in 2014 and was known in paranormal circles for operating on people who claimed to be alien abduction victims. The objects Leir extracted, Delgado argued, were proof of an ongoing colonization — one conducted without consent, hidden inside a liquid interface delivered to billions. Audience members shifted in their seats, held their melting ice cream still, and reached for their phones.
A search of Delgado's background told a fuller story. He had helped organize a three-thousand-person anti-vaccine protest in Madrid in September 2020, had refused to send his daughter to school over fears of transgenic exposure, and had founded a YouTube channel — La Quinta Columna — that the platform eventually shut down for spreading vaccine misinformation. When pandemic anxieties cooled, his movement simply absorbed alien abduction narratives and kept going.
The booksellers of Vallecas filed a complaint with the municipal government. Councilor Félix López Rey of Más Madrid called it intolerable that a public cultural event had been used to platform unfounded anti-vaccine theories during prime time. The fair continued around the controversy — poetry, storytelling, the ordinary warmth of a Saturday afternoon — but the question of how such a speaker had been programmed in the first place remained unanswered.
On a pleasant Saturday afternoon in Vallecas, under the shade of trees lining Peña Gorbea boulevard, families gathered at the annual book fair with ice cream in hand, expecting the usual mix of poetry readings, puppet shows, and neighborhood history talks. Instead, they got something else entirely. Ricardo Delgado stepped to the microphone in front of roughly a hundred people to deliver what he framed as urgent scientific truth: humanity is being implanted with microchips by an alien species, and the evidence is hidden inside vaccines.
Delgado's presentation drew heavily on the work of Roger Krevin Leir, an American podiatrist who died in 2014 and became known in paranormal circles for performing fifteen surgeries on people claiming to be alien abduction victims. Leir extracted objects from their bodies, which Delgado said he had studied. According to Delgado, these implants contained what he called stellar microwaves—essentially 5G technology—along with carbon nanotubes and graphene. All of it, he insisted, had been introduced into the human population through vaccines delivered as a liquid interface. The implication was staggering: an entire species was being colonized without consent by another species that had always been here, always in control.
The audience reaction was visible and immediate. People shifted in their seats, scratched their heads, held their melting ice cream motionless. Some pulled out phones to record and post what they were hearing to social media—an unusual move at a literary event. Delgado continued with escalating certainty, describing this as the gravest thing to ever happen to humanity, claiming to possess scientific proof. The talk was titled "Transhumanism and Intracorporal Technology," which at least signaled its subject matter, though for attendees expecting author interviews or storytelling workshops, the pivot was jarring.
A quick internet search revealed who Delgado actually was. In September 2020, he had helped organize a protest at Colón that drew nearly three thousand people opposed to vaccines and masks. Months earlier, he had given an interview describing his refusal to send his daughter to school out of fear she would be exposed to a transgenic virus through vaccination, masks, or PCR tests. By training a fitness instructor and by credential a statistics graduate from the University of Seville with a master's degree in biostatistics and immunology, Delgado had founded a YouTube channel called La Quinta Columna. YouTube itself had shut the channel down for promoting vaccine denial and misinformation. After the pandemic faded and vaccine anxiety subsided, Delgado's movement had simply rebranded, merging alien abduction narratives with 5G conspiracy theories.
The response came from an unlikely quarter: the booksellers of Vallecas. They filed a complaint with the municipal government. Félix López Rey, a city councilor from Más Madrid representing the district, called it intolerable that the local municipal board had scheduled a speaker to promote unsubstantiated anti-vaccine theories during prime time at a public cultural event. The irony was sharp—while families sat in the afternoon sun expecting literature and local history, they had instead received a presentation rooted in pseudoscience, delivered with the confidence of someone convinced he held evidence the scientific establishment refused to acknowledge. The fair continued around him, poetry and storytelling and the ordinary pleasures of a Saturday afternoon, but the damage to the event's credibility had been done.

The Hearth Conversation Another angle on the story
How does someone with credentials in statistics end up promoting theories about alien implants?
That's the puzzle, isn't it. Delgado has real training—a master's in biostatistics. But credentials don't inoculate you against believing what you want to believe. He started with vaccine skepticism during the pandemic, built an audience, got deplatformed. Rather than retreat, he pivoted to a bigger narrative that made him feel like he was uncovering something hidden.
Why would a municipal government book fair even program him?
That's the question everyone was asking. The title sounded academic enough—"Transhumanism and Intracorporal Technology." Someone approved it without apparently checking who he was or what he actually says. It's a failure of vetting, or maybe just bureaucratic inattention.
What did the audience actually think was happening?
Confusion, mostly. People came for poetry and neighborhood stories. Instead they got claims about species-wide implantation delivered with absolute certainty. Some recorded it. Some just sat there unable to process the disconnect between the setting and the message.
Does he believe what he's saying?
That's unknowable. But he says it with conviction. He's built an entire worldview around it—the implants, the 5G, the hidden species. Whether that's genuine belief or performance at this point probably doesn't matter much to the people who heard him.
What happens next?
The booksellers complained. A city councilor called it intolerable. There will likely be questions about how this got approved. But Delgado will keep speaking somewhere, to someone. The narrative is too compelling to him to abandon.
