"I said no!"
"I won't give up until you do!"
"Fine, I'll watch the show. I didn't say I would like it!"
This was the conversation that went on when my friend Anna was trying to convince me to watch Doctor Who. I eventually agreed to watch it, and by the third episode I was in love with the series, as I am still. If I had not bowed to watching her interests, I never could have found the love I have right now for Doctor Who.
In addition to finding a new TV show I liked, I also was able to adapt to what Anna was interested in. For Aspies, this can be hard: we have our strict routines and don't like having them disturbed, especially by new, fast and sudden change. However, if you don't try to show some interest in what others like, you may never discover you really like something, especially if your friends are trying to introduce it to you. They are like you, so maybe you will like it too, give it a chance!
However, there is always the time where you absolutely cannot stand something that other people, even your friends, like. It's stupid, or pointless, or both, and you cannot interest yourself not matter what you try. Don't tell them how much you hate it, but rather try to smile through it. It may not be your passion, but these people support yours, so it is important to support theirs, be it TV show, book, movie, or game. They would do the same for you.
In short, Aspies, give a bit of change a chance. Maybe you will find you love what your friends share with you, and if you don't, try to tolewrate their obsessions, because they do the same for you.
