The ASD people that I've met are really annoying. Some were cool, one or two will end up being good friends of mine. But the rest (~10 of them) were really annoying. Basic things like eating with their mouths open, one guy ate like a frog and could be heard from the other side of the hall. Another guy talked way too much, and had no idea people weren't interested. I had to avoid him as any sign of availability to listen he would jump on, spamming you with facts about history (his special interest).
Now, NT's are also annoying, and also do all of the above. However, these people seem to be less common. For example, if you took two control groups with 10 people in each group. Group 1 was full of autistic people, and group 2 was full of NT's. 7/10 of the autistic people would infuriate me while 2/10 of the NT's would infuriate me. I hope that makes sense. Now it's arguably because of my heightened sensitivity to my surroundings that I find autistic people annoying, because of my own autism; ironic right. So I can't really speak for how NT's might find autistic people annoying, as I'm not one, and as they tend to be less sensitive to their surroundings and lost in their own lives.
