This is controversial of course, but I followed Kris Nova pretty closely and after some time I saw her trying to funnel her audience into a slack instance (or something like slack, might have been discord).
When I reviewed the rules, which I tend to take seriously I noticed that it said "We promote neurodiversity" and in the next line it says "don't be an asshole".
I understand that some people can see a distinction here. The problem I have with those two rules is that if you are a person who is autistic, your behaviour is seen by neurotypicals as "being an asshole", especially on text based mediums where communication is much more limited in context and less rich meta-communication like body language or tone.
When I pointed this out, I was blocked.
I can only gather that people want to be seen as inclusive, so they use things that are easily seen. That which is _not_ easily seen is ignored, like autism- though people will say they support people with it, I think they're not actually interested in understanding that autism isn't just being a bit anti-social, it's a mental illness and it can be difficult to live with! Another minor example of people not caring what cannot be seen: I don't see many people making a stink about economic background, but that is a massive differentiator in mental diversity.
