He does not have to be white to be Spiderman, as it is fine to have someone else plat him as a different character, but since peter Parker has been welle stablished as he is white...
it would be like having a Black batman , that would be fine also, just make him a different person, not bruce wayne,,,
Again, you're just saying "Peter Parker is white because he is". You aren't convincing me it is a core part of the character, like Mangeto being a Holocaust survivor and Jewish, or Daredevil being Catholic.
To me, that's the standard when it comes to changing a characters race, ethnicity, upbringing, religion, socio-economic background, etc... If it isn't core to their character, why does it matter?
Is there a reason a black actor can't play Bruce Wayne? I don't see why not.
