Replying to Mainstream "cleaner" than underground?

So recently, my parents have gotten a little pissy about the music I listen to, yes...im 16. I mainly listen to Wiz Khalifa, Currensy, Biggie, Nas, Waynes old shit, Pacewon, Big Boi, Eminem etc...Now I have a sister who's 13 and her and my mom listen to the mainstream music (Flo Rida, B.O.B., Katy Perry, Ke$ha etc...) So today were listening to some gay ass song and they say "come lay with me, i want my fantasies to come true" and that was the chorus. So i said, "mom how can my little sister listen to this but I can't listen to my music? Their saying the same thing just in different words."...yeah, give or take fuck, shit, bitch and hoes...but you get the idea...does anyone else agree with me?
