Is it weird that I like...?

Other kids at school LOVE My Chemical Romance, but I hate them. I'm more into HSM, Miley Cyrus, Green Day, Aly and AJ, Natasha Bedingfield, Kelly Clarkson, and AC/DC. I'm only 12, and I think that everyone's growing up way too fast. Everone says HSM and Zac Efron is gay and Miley sucks. I thought parents actually want their kids to listen to this kind of stuff, but not mine! They hate HSM and Miley. Should I speak up?
