Because most of the times white characters are white because it's the default race to be. So their race generally isn't notable or relevant to the character.
How is Daimo's race relevant to his character
doesn't matter. there is an opportunity for an Asian to get cast, and that looks great for American progression. less people feeling alienated because more would feel included.
why's this a problem?
Because identity politics is a cancerous worldview and saying it's ok to replace one race but none else is regressive. That's all.
is it only regressive when it's not in your favor? this country was literally founded on identity politics, and you seem to take issue with those who feel like they got the short end of the stick in representation.
why can't we be included? why draw the line at people of color?
Why does an Asian actor have to play only Asian characters? Why is an Asian character an "opportunity"?
you're replying to the wrong person because I never said "only."
are you opposed to Asian actors finding employment? what sort of question is that?
