Well, it is a rather multilayered phrase. And sarcasm is present there too. And yes, I really think that most of the US citizens are racists.
Most white people are racist.....including the majority of Europeans. Just ask your average European about the Romani people and you'll get to hear some "interesting" opinions.
(I suppose this is exactly the case: the "woke" US citizen mumbling some racist shit while being sure that he is being super anti-racist).
Pointing out that international media has biases when it comes to ethnicity is not racist. Claiming that racism is not a problem in Europe, or that European news is devoid of racial biases is racist.
Always glad to know .....and I'm guessing here, that a white dude from one of the most privileged places in the world still think of themselves as the authority when it comes to defining racism.... It's reassuring that some things will never change.
