Why is Mincecore not called Mincegrind?

From what I understand, mincecore is a subgenre of grind that which the purpose is to be anti-homophobia and anti-sexism. The name comes from the word 'Mince' (death to homophobia and sexism) and -core. But that makes it sound like mincecore is hardcore that is specifically anti-homophobia/sexism whereas (from what I understand) mince is really grindcore which is specifically anti homophobia/sexism. So why is it called Mincecore and not Mincegrind. It sounds misleading. You would never call deathgrind deathcore, as those are two completely different genres. So why have they done this?
