I know what colorism is, but things change, and I specifically mentioned this because you said "she wasn't light-skinned in the comics". I wasn't talking about colorism as an idea on some grand scale, but the idea that they race-swapped her in the movie. Producers are "altering races" to appeal to wider demographics, just like they are doing to some white characters now. Just like they did with Halle Barry.
I think it's an interesting thing, where colorism is obvious and right in your face for black people, but for white people, they might not even notice it. And then right now, you have a shift, where some white characters are changed and black people just view it as diversification, while for some white folks, it feels as offensive as colorism does for black people.
Also, regarding the "I never said "Are you black"?" line. You kinda did. You said:
"Are you black or a POC? Because you would UNDERSTAND why I can."
I don't really give a shit, but I have heard this line a billion times when talking to black americans. Immediately when you mention anything about race you get this stuff thrown at you. It feels like someone is telling you "stfu white guy". I know you didn't say that and I am likely just misunderstanding, but it's just a strange thing.
And frankly, I don't think we are that misaligned on all this, I just reacted to the idea that Halle Barry should have been darker as a weird one.
