I'm a neurotic Caucasian. I must organize stuff in certain ways. Black People, White people, true metal, false metal, cheese, sugar, everything else.
Plus; just because it's false metal doesn't mean it's false music. I just call it false metal because it doesn't fit my own criterion for true metal. I consider the two groups to be completely different, aside from the fact that they have distorted guitars. To me, to say your top ten banRAB or whatever and have a mix of metalcore and nu-metal with death and black metal, it'd be like mixing in jazz banRAB or hip hop groups. I dunno, I'm nutty that way.
I like both true and fake metal. Never said I didn't.
