Oh I was waiting for that one! Look, it's really
your problem if you perceive that metalcore bands are actively killing and and maiming people who listen to "true metal." They're not; it's just a different kind of music. I know a lot of metalheads get this idea that they are an enemy insidiously trying to bring us down, but it's almost as bad as Satanist black metal bands fighting their nonexistent Christian god enemy
hilarious, just fucking hilarious. Aren't you like 14 years old? Can't you think for yourself? Your post is just ridiculous and sensationalist sounding, tbh.
Also, metalcore isn't one of our latest inventions because it has been around since the early 90s and I'm pretty damn sure someone in America has invented SOMETHING since then
