My social skills were dreadful until I had some psychotherapy in my teens, but even now they aren't that great. And same as with OP, a lot of things that 'normal' people like are foreign to me - clubbing, watching sports on TV. I'll also add to this list - alcohol, smoking, nearly all TV series / shows.

But I never thought I'm 'on a spectrum'. Since heterosexuality is also completely foreign to me - I just assumed I'm a minority in most other areas too ;-) I had to have a long adjustment to the idea that despite being a part of a persecuted minority - there's nothing wrong with me. It's the society that is the problem - not me. Being in a majority is not a proof of a validity of your views - it is just an easier way of living, because you don't have to think about anything. And once you do that mental adjustment once - it is easy to apply elsewhere. I think that watching TV is a waste of time, I'd rather read a book - so what? I'll politely nod when someone is excited about yet another insufferable TV hit series, just as I will politely nod when they are talking about their heterosexual marriage / kids / suburban utopia. I don't have any desire to join in.
