I think I would probably love it but I don't know if i find it unfair to exclude NT's or other disabilities, mainly a personal matter because I've been left out so much. So yeah, I would use it but i'd expect a backlash of society disagreeing with it because it excludes other sectors and then it would be closed down

because we are allowed to be left out but its not morally correct when they are (apparently). I think it would make a much cleaner supportive version of facebook though (especially without the virtue signalling posts and pictures).
It's a little controversial and I most definitely don't mean any offence here, but in some situations segregating can isolate certain minorities in my opinion as it's making a point that they're "different" and if they're not different except for something that should be totally irrelevant like the colour of their skin it's in my opinion unnecessary and could even encourage prejudice. For instance when I was working for a local council I found that the
Unison trade union have black members only meetings and make a big issue of specifically supporting black people separately with quote "Black members’ representatives", please
click here for example. In my opinion there should be equal rights and I am most definitely not racist, but having black members only meetings where white people are normally not allowed to attend is only isolating black people and is making a point that they're black when it shouldn't be an issue in the workplace or in fact anywhere else. Okay I understand there can be a mutual cultural interest, but this isn't in my opinion significantly relevant enough to create such segregation in a place of employment.
It is different in my opinion with people on the autistic spectrum however as even though there also shouldn't be any prejudice we are in fact significantly different from NTs and some of us also have specific support needs. I therefore think it's okay to have services specifically for people who really are significantly different or have a relevant common interest. Even though a social network for people on the autistic spectrum or anything else just for people on the autistic spectrum can still somewhat isolate us from the rest of society, it can also be advantageous to the autistic people using the service. Regarding other minority groups being excluded and any potential backlash, well an autistic charity such as
The National Autistic Society doesn't get condemned because they don't also specially help NT people who happen to be in a wheelchair for instance and there's lots of services that are for specific minorities. I don't think anyone should be forcibly excluded from joining, but it is okay to make a social media site that is aimed mainly for autistic people and it's therefore unlikely that many NTs will join unless they have a specific interest in autistic people themselves (similarly to this community, but a social media site will probably have an even higher percentage of people on the autistic spectrum).
If people are joining the site in the hope of making new real life friends or perhaps to find a partner however, then even though a lot of autistic people get on well together, sometimes their traits can also be detrimental to each-other and can cause friction, E.g. one person is over sensitive to noise, usually wants quiet, while the other person shouts because he/she can't control the level of their voice and is unable to stop repeating and going on about things all the time. In this case the person would probably get on better with some NTs and I also don't think autistic people should exclude NTs as potential friends or partners.
