Your rant breaks down to white+straight+male is the default, and you need a specific story-driven reason to deviate from that.
Call me crazy, but even as a white straight male, I have enough empathetic capability to be able to play as, say, a black lesbian female and not freak out about it.
In other words, you didn't read a single word.
I said, diversity is fine for NEW IPs. I love playing as female characters, for example. BUT WHY CHANGE OLD STORIES AND CLASSIC CHARACTERS WE LOVE INTO DIFFERENT VERSIONS THAT THEY SIMPLY AREN'T SUPPOSED TO BE?
PLEASE READ BEFORE COMMENTING.
