I don't wake up in the morning and say to myself "I sure hope I continue to believe that the Earth is round by the end of the day!" That's crazy: I have no vested interest in that belief. I believe the Earth is round because the evidence is overwhelming and the contra-evidence is unconvincing. I'm not worried that someone is going to come along and erroneously convince me the world is actually flat -- I trust my own judgement more than that. Unless, of course, the world actually is flat, in which case I'd want someone to convince me of it! It's the truth I have a vested interest in, whatever that truth actually is.

It sounds like it's important to you that you make sure to not like mainstream things, so that you can look down on people who do. I encourage you to get over this. The more things you let yourself enjoy, the more fun you have in life. And you'll like yourself more too, knowing you're not being as much of a condescending prick. Trust me; I've been there.
