For me it depends on who the people are that I might feel accepted or rejected by. I seem able to get on with pretty much anybody, but I notice differences in outlook and perspective that are often so great that I wouldn't last long if I had to live among them indefinitely. I can only stay accepted at all with them by hiding a lot of who I am, and that's a very empty experience for me, because to me they're not really accepting me, they're accepting a mask I feel I have to wear to keep them sweet. Luckily there have been people with whom I've needed to do very little masking, and it's with them that I feel accepted in a much more profound way. Of course it's rarely completely binary, most individuals are somewhere along a line between the two extremes.
The question is hard for me to answer because I don't approach many people, I very rarely ask to hang out with them socially, so I don't often find out whether they'd accept me or not, because I don't often give them anything to accept or reject. I don't really look for friends, I just wait until either they find me or circumstances (such as a common interest, especially in music) push us together and we find out whether or not it works. I don't think I've ever so much as sent a Facebook friend request. I guess, considering how non-proactive I am in that respect, I must be reasonably popular and likeable, or I'd be completely alone, and I'm not.
