I think you're a little fixated on race.

They're 'limitations' in the sense that one skin colour is good for facilitating Vitamin D, which means the darker-skinned folks might have to take supplements, and the lighter-skinned folks have to use more sunscreen since white skin isn't conducive to skin cancer prevention. They're minor inconveniences. They don't limit who we are as human beings, or our value, just certain things we can and can't do, because of biology. It's just more dramatic when you compare male to female, because men clearly are much stronger and historically far more of a threat to women (and also other men).

Noses evolved to suit the environment, as did eyes & other features. It only makes you 'better' at living in that environment. Look, dude, I put on sunscreen when I go to the beach because I'd be an idiot not to. Have you ever had your D levels checked? From what I found the other day when I got to wondering, "Are black people at risk for Vitamin D deficiency?" it was yes, although I couldn't be arsed to find out if that meant you got anemic, or grew a second head out of your shoulder, or what.

Why is it such a big deal to accept that there are certain differences between people with The Element Formerly Known As Race Before It Became A Political Clusterfuck? Call it whatever you like, it's evolutionary differences that exist between people and they're clearly an obsession for some and engage Sudden Visual Blindness in others. "What? What? the guy in the red shirt! The guy with the poufy hair! The guy in the red shirt and the poufy hair! That guy there! By the water fountain! That's the guy who can help you!"

"You mean the BLACK GUY?"

<muttering> "Well...uh.............................yeah."

'Race' differences are clearly a thing, one side wants to talk about them and the other side doesn't...and I say, why not just acknowledge it and move on. Why argue about whether 'race' is a social construct or not when in fact what we call 'race' is surficial differences that will only stop being a big deal when we stop making it a big deal. But let's not pretend those differences aren't there because they clearly are. Maybe we'd all care more if Josh Hawley tried to join the Nation of Islam and Kanye West tried to join the Klan. (Well, they'd find common ground on Jews anyway, I guess.)

Pretending 'race' doesn't exist strikes me as bizarre as claiming 'sex' doesn't exist or isn't real.
