I get along with other autistic people about the same way I see non autistic get along with other non autistic people.
I find that I am able to connect with most of autistic people just fine. Communication is fairly natural. I don't have to dedicate a whole lot of energy when hanging out with these folks. If I'm not close friends with them, I can still spend some time with them and enjoy it in most cases. Every autistic person is different of course. Some are assholes. Some are nice.
I have a few in mind that just absolutely grate on me, though. One in particular will interrupt you while you are talking. They say they can't help it, but it does make me lose my train of thought and then I forget what is going on. And if you have a hard time keeping up with them (due to sensory overload), they will say you're not worth talking to and exclude you from the group. I find this person very difficult to get along with and very strongly dislike it when they show up to gatherings I'm at. I don't meet many autistic people I dislike a lot, though.
To contrast with non autistic people, I find it very difficult to communicate with them. I struggle with remembering context and subtext and have to take a lot of energy to constantly include this in my listening. I feel like an alien trying to communicate with the humans. A fair amount of people don't have the patience to talk to me or know me as more as an acquaintance, but there are a handful that don't mind my shortcomings. My friends that are not autistic, I like but it is far more exhausting to talk to them.
