wow, i was literally JUST thinking about this sort of thing this morning!!
when i was in 6th grade, i really really liked these science fiction books, Animorphs. My best friend and i were obsessed! So we got made fun of...a lot. i still remember the boy, and i remember how much i hated him for it!! Admittedly, liking SciFi is pretty geeky....
so i was thinking how funny it is, that at age 23, how i am COMPLETELY accepting of the fact that i'm still a nerd, and even moreso, pretty much everyone else is okay with it too. My friends may give me crap about it once in awhile, (but not like, real seriously) but we all know i'm a geek, and it's totally okay!
i mean, i'm not a
total nerd.

But my love of Disney, and SciFi, and video games, and things like that do make me pretty nerdy. i like to think i'm well-rounded, though; i did theater/chorus in high school, played rugby in college, and now i'm a cheerleader. i know, fab resume.

haha
i guess my point is, everyone likes what they like, and not everyone else likes what another person likes. Unfortunately, people at your age tend to be really cruel about these things - why, i have no idea, and i really wish it weren't true. Maybe it's overcompensating for things that they're insecure about, or maybe they're just jerks, who knows (both are likely to be true, to some degree, anyhow.

).
BUT I PROMISE YOU...it gets better. No, really! i know it's hard to hear that from older people, but HEY i'm 23, i'm not that old yet!! i really do remember this crap, and how hard it was, but REALLY, it does get better.
until then...your mom is right, the best thing to do is ignore it...even if it is the hardest thing in the world.

But learning to ignore what other people think is definitely a life skill, so working on it now will deffo give you a leg-up on your peers when you get older. If you don't hold yourself back because you're afraid of what other people will think of you, you'll be able to accomplish wayyy more than the idiots judging you for having a passion. UM, hello - 3 young boys just won a Tony award for their dancing, and i'm sure they faced their fair share of taunting. i would MUCH rather say i won a Tony, than say no one made fun of me that day.
i swear, once you get older, you'll find other people that like the same things you do (hello, DISboards!) and you'll be able to band together. Even better, people around you will grow up, and realize that even if you do have your differences in interests & personality, that doesn't mean that people can't just be cool and friendly to one another. No, really, i swear this happens...to most people, anyway.
sorry for my book. It really is coincidental how i was thinking about that this morning. It really used to get me if someone made fun of me for something i liked - now, i really could not care less if someone thinks i'm a nerd or i'm weird for something i like. Learn it now, sweetheart: love yourself, no matter what. i know it sounds soooo cliche, but forreal, as long as you're cool with yourself and you're not hurting anyone else (and, uh, not disobeying your parents, of course! because i never, EVER did that...

), do whatever you want to do, and LOVE IT.
