Just because Bubba Wallace is light skinned doesn't make him close to being white. He still would've suffered racism like other black people. Racists don't give passes to people who are mixed race. You will still get called the n word or be discriminated against for your looks.
I'm sure some do assuming they can identify you as such. This depends on choices a person makes with regard to how they present themselves.
I had no idea Rashida Jones was Quincy Jones's daughter. I assumed she was white from her appearance on
The Office for years. This is what Halsey means when she talkings about being "white-passing" despite that she isn't white, either. Were you aware? I wasn't. Not until the Floyd protests broke out and I read an interview with her because she participated in the protests. I'm willing to bet a lot of guys on Sherdog had no idea she has a black parent. If I worked for some institution, she came in, and filed some document with me where she only checked "White", I wouldn't have questioned it. Same with Rashida.
Bubba reminds me of Blake Griffin. The blackest thing about them is their hair. Straighten that and I might just think they had a deep tan. I might notice slightly darker skin, so that I would wonder if they had someone of dark skin somewhere in their family tree, but it would be a mystery to me. Native American, Polynesian Islander, Latino, Black...I wouldn't know, and I'd be as likely to assume one parent was white, and another light-skinned of this mysterious origin. Wentworth Miller is another example that comes to mind. No idea.
This is where that "spectrum" of race becomes valid. I'm not saying race isn't real. I'm saying there's a spectrum that's important to perception. Yet, in this instance, when it is convenient for those holding liberal political views to deny it, or laugh about it, those who have most widely embraced the "race isn't real!" slogan in the past decade suddenly acknowledge again that race is quite real. They laugh at the space where it legitimately blurs.
