My local queer events are full of NDs since there is a large overlapp, same with pen-and-paper groups, progressive and IT meetups.

Sound a bit like a stereotype, but from personal experience all these places are full of the NDs or people who are generally very nice.

I know personal meetups are not always possible or easy to do, its just the option I had the most success with while having fun in general.

Duolicious although its full of 4chan people there are some actually neurodivergents. Its not monetized at all and have modern interface and features. I saw few neurodivergents on Hinge, and OkCupid, although it will require tones of swiping to find them. Check "I am autistic, now what?" youtube channel, they have discord community, i didn't check there tho but was planning, i just dont like discord. Check Ember Green youtube channel too, they might have something similar. In short: Duolicious app and "I am autistic, now what?" youtube channel discord community. I am for almost 2 years in social isolation in a place where i dont know anyone and dont speak local language, i understand how hard is it

It works perfectly for me. 5 likes a day is so much that I couldn't keep up if I was using them all. Have already met several nice people through it.
