Just wondering, considering how the internet reacts to racebent character portrayals. Personally, I'm generally indifferent to this kinda stuff. I see it like this:
"What is this race debate?
Outrage culture is getting annoying, on both sides. Either it's a PC agenda, or someone is a bigot for having an opinion. In regards to these race bending casting, to make it neutral, how about this:
1) Is the character from a real place, with real ethnic population numbers?
2) Is the race of the character important to plot?
3) Is the race critical to their characterization and development?
4) Does race play a part in their interactions with other characters?
If the answers to all those questions are "No.", then an open casting call it is. The the role can go to anyone, as long as they earned it or are talented enough for the role."
However, Erik checks all those boxes.
On the other hand, I don't want an old Magneto. I want one that's physically in his late-30s to mid-50s. So I wouldn't mind them changing which genocide he's a survivor of. I thought it would be interesting to see a 5-6 year old Erik saved from the Cambodian Killing Fields, or see a teenage, Tutsi Erik have to survive the 100 day Rwandan genocide being hunted by former friends. The Balkan Wars work just as well, if we want to keep him white.
This all about keeping him young(er), which adds in other potential character elements (like Erik being one of Xavier's first students, and the leader of the first generation of X-Men, for example).
So yeah, how would you react to a potentially Cambodian or Rwandan Magneto? Does it make sense, or not?
