Hello everyone. I just have a few questions.

I am a young man and I have my ear pierced, am I going against god?

I also listen to some modern heavy metal bands, (Trivium, Bullet for my Valentine, In Flames and Korn) am I sinning by enjoying their music?

Also, there's a pro-abortion and pro-gay rights group at my school, I'm very curious as to if anyone can point me into some bible verses that I can inform these people about.

Thanks in advance for your answers.
