I've never liked alternate takes on characters. You want to run with a different idea? Then build a new character around the idea. Whether it's a no holocaust Magneto, or making Superman gay/trans, whatever... if these cunts had any creativity or talent they'd be able to make something new instead of destroying what is already great.
It reminds me of that Star Trek: The Next Generation episode where the race speaks based on their stories: Shaka, when the walls fell. It works when everyone understands the references, which their race does and the Enterprise crew does not. Changing the characters --motives, race, etc-- removes our ability to relate to those characters because now we have to start with, "Which version?" instead of, "Of course Captain America/Superman did that... he's a Boy Scout." It's annoying as fuck.
