I am having the time of my LIFE seeing USians short-circuit when they see a tanned White person (in my country, Greece, this is "tanned" White) and their race theory crumbles because soooo many admitted they clocked him as White. Well done people, you are sooo close to realizing that the White/Caucasian type has diversity in it! They are so desperate to "clock" what is this "weird" type of person who looks and doesn't look White!
Actually, people who look like him you have already categorized as White, not only in your legislation but in your social life as well (we are called South Europeans!)
I have news for you! Your sense of categorizing people is fucked up and the reason you short-circuit like this is because you follow the outdated standards of pedantic, classicist, and rich assholes! And the proof is that the MOMENT you learned about some "ethnic" background you rushed to see his dark hair, tan, and features with a totally different eye.
Here's what you miss. It's oversimplified and cookie-cutter but that's apparently what you need to understand how the world works.
