Stop trying to make yourself one dimensional. Existence precedes essence. You aren't a nerd, you're just a dude, that does nerdy things sometimes. The things you do aren't you, and you aren't them. If other people want to do the things you do it does not detract from your enjoyment of them one iota, unless you're so self absorbed you can't enjoy it without exclusivity.
As I tried to explain in comments downthread, it's not about being detracted from enjoyment because new people are arriving to the scene. It's about that what was once a refuge from bullies is no more, because the safe harbour became mainstream interest, and now "weirdos" are being pushed back again by the society that requires you to conform to its definition of "normal life" and "normal interests".
