"I'm the most advanced autistic martial artist in the world, as far as I know," he says later at a café. He vetoed an earlier place because he didn't like the light and the noise, but here seems more relaxed. Underneath his calm, he is a fierce activist.
"There is no non-autistic person trapped beneath the autism just like there's no straight person trapped beneath the gay," he says. Sussing out how the narrative of autism evolves is a part of his work. He sees parallels in everything from colonial Africa to 20th-century feminism to the gay rights movement, and parallels in repression.

"If we didn't have value in hunter-gatherer society, we wouldn't still be around," he says, reflecting research that argues that the autistic mind — visual, spatial, logical — has been necessary to push the species along. From creating the perfect spear-point onward, there has been a line of unconventional thinking in the species that, some scientists say, points to the prevalence of autism throughout time.
But just how, or why, is autism still around, if it causes so many problems? How are autistic people reproducing enough to push that constellation of genes down the line? One thought is that those genes that code for autism are related to intelligence. Dr. Hagerman and others believe the fragile X protein, for one, is deeply involved in cognition. That having more of the protein makes you smarter, able to learn more efficiently. Maybe autism is a natural consequence of the evolutionary experiment in human intelligence.
Whatever the case, says Walker, autism has been a permanent feature of the species. "We're part of the gene pool," he says. "And we're part of it for a reason."
To understand one another better, it may take both activism and science to find common ground.
As Cari Wheeler says about Max, who with this new drug seems to express himself better and demonstrates emotions she never saw before, maybe it was something he'd been feeling all along, "but we would've never known it. He's kind of in our world now."
Which works both ways: Back in the café, Walker is explaining how he experiences the world. He's synaesthetic, his senses blending so that light, color, smells all blur and merge. He very much enjoyed hallucinogenic drugs. But he really enjoyed taking drugs with his neurotypical friends. "I love non-autistic people when they're on acid," he says, because they can, finally, "come and play in my world with me."
