You are technically correct; people can absolutely be racist against white people.

Now I'll explain why you're being downvoted anyway.

"Black Lives Matter" became a slogan because police disproportionately target black people. They stop and question black people at a far higher rate than is warranted by actual crimes, they arrest people at a far higher rate than white people, and they kill black people at a far higher rate than they kill black people.

The statement is very obviously not just a literal statement on the value of human life; it's an accusation that police seem to think black lives don't matter. "All Lives Matter" simply pretends to be ignorant of the entire background and reasoning behind the phrase.

Israeli's have been massacring Palestinians and leveling their cities. They have inflicted orders of magnitude more suffering on Palestinians in the last years than Hamas has during its entire existence. The only way to equate the two is if you believe that Palestinian lives are worth significantly less than Israeli lives, and yes, that would be racist.

Yeah that's just called racism. White people don't get a special prefix when it happens to them.

But it is a thing... People can absolutely be racist against white people.

It's not a thing. If someone hates another person based on their race, that's racism. This idea that it only applies to hate towards black people is very much a US only issue. The rest of the world understands that racism towards any person is wrong.

Technically you could argue that "reverse racism" would be explicitly liking someone based entirely on their race, and nothing else. But even that's a stupid way of looking at it.

Read the room.

I think the funny thing about racists is that they don't care and it doesn't have to be consistent.

I did not mean to imply that the idea of race is legitimate.

Yeah. Race, in general, is a fundamentally unsound way to categorize people. Humans are clinal in every single characteristic associated with race. Attempting to boil a multidimensional continuum down to a binary distinction is a fool's errand.

And jesus isn't real either but christianity still exists.

'Black' isn't a race either.

That's not how the racists that use that word, use it.

Hating people who have nothing to do with your oppression because of their skin color is racist. Full stop.

It's like saying men can't be raped because women are the majority of victims.

No, it's apparently white people who think they're being systemically discriminated against.

I incorrectly thought it was more of a way of saying that you can't be racist against white people.
