Im a christian but christians piss me off?

yes i know this is a statement but idk how to put it as a question. anyways like said before, i believe in god till the day I die but seriously christians piss me off , they think anything is satanic, a few days ago i went to a store, and told me to burn my shirt, it was just a misfits shirt, wtf! misits arent satanic. I hate how christians think rock and metal music are the devils music, the devil was around way before either genre was made, plus those who say that cant name one song and just listen to rap which is way worse (IMO) than either genre. Metal seems to get this misconception alot but people think thats screamo which isnt metal its hardcore and neither is satanic. My moms starting to tell me my shirts are satanic but doesnt even talk about satan and most of the band members in bands i listen to are christians and born again christians, I wear misfits, Iron Maiden , Metallica, Judas priest, Testament (hows that a satanic name?), and my mom wants me to throw those away, trying to make me look like a freakin jock, she tells me all the kids arent wearing those but idc, I wear what I want, they dont scream, and theyre not satanic! and whoever thinks its satanic name one song
