Christian Metal, Hypocrisy, right?

Now first off, im a metal lover, (and rap of course), and i have nothing against the christian faith, i believe in God and Jesus, i just dont read the bible much, or go to church. Well for years, Christians Shunned us Metal listeners, back then they even shunned rock and roll listeners, they found both listeners and lovers of that music to be dirty, vengeful, followers and worshippers of Satan, and even now that lie still resides in some, yesterday, i found a question on here, of a kid, who loves metal, asking if people who listen to this stuff, worship Satan and "Hitler"? can you believe that? Hitler? he said that was what his sister said. but now, here in this time, are people who play "Christian" Metal, "Non-Black" Metal, and i just cant believe my ears, how can they call us "anti-christian" and then think they can use this genre to spread their belief? its just absurd, right?
