They want to get a bunch of neuro divergent people in an enclosed space in a crowd.

Can't think how that can go wrong

The idea is potentially interesting, though I'd wager that many cons already are autistic & neurodivergent conventions (honestly, everything ranging from defcon to comic-con to burning man).

Buuuuut... it might be a bad idea to use the tools of those currying favor with fascists to create a list of one of the groups of people targeted by said fascists. Just a thought.

Isn't that just any anime or furry convention?
