In high school I once had a popular mean girl decide I would be her lunch hour entertainmet as I was the introverted geek girl. I was wearing a tee shirt for an old punk band I liked and she spilled ketchup all over it and told me she did me a favor by making it look better. 

Skip ahead to my college years and some noteable pop singer has a stylist who puts her in that same tee to be edgy. See said mean girl in that tee sometime later. Get into bitchy spat with her using stuff I love as a fashion accessory. She claims she loves the band but never gave them a chance because she only ever saw losers like me into them. And this is one example of many. I carried quite a bit of angst over that for years. So I see where you're coming from and agree. I wanted to smack the bitch. I didn't feel like she had the right to insert herself into my corner of the world, especially since I was treated like the weirdo thete but it was suddenly great when she liked it. Yup, lotta angst back there.

At the same time, speaking from a decades later perspective, it's nice to see more of the world realizing stuff me and my friends love has value and they can get into it too. Probably feel even better if some of them had to get crap everyday simply for trying to be themselves and liking what they liked, but such is life. It would be nice if we could all just like what we like and anyone with a different opinion just kept it to themselves. I think I shed a lot of my agnst when I felt the reality that is adulting. There's just not enough time in the day to waste carrying that baggage. Of course (like now) the internet likes to remind me.
