How to convince my parents that hollywood undead is a good band?

Hey im 14 and in 9th grade. And my parents flipped out when they found
out some of Hollywood Undead songs. Now, I know they mostly sing about
sex, parties, drugs, and so on. But they do have some really good
meaningful songs like paradise lost, circles, coming back down. and
much more. I LOVE this band and always will no matter what my parents
say. And lots of my friends listen to hollywood Undead to. But please
help How to convince my parents that hollywood undead is a good band?
thanks :)

P.S. NO RUDE COMMENTS ABOUT THE BAND. THERE A GOOD BAND AND ANY1 WHO
DOESNT LIKE THEM HAS NO LIFE ANSWERING THIS QUESTION ANYWAY.
Also my parents don't like how the band wears masks and has a bunch of
tattoo's
