I'm not really sure where to begin with this, so let's start with a few points of agreement. Racism is a learned behaviour. I think you're absolutely right about this (though being white very obviously isn't).

You also say racism was invented, which I also agree with. I even included a link in the article which goes into detail about its invention.

The idea that whiteness is also true. But the current formulationof it certainly is. As I point out, the poster that appeared in The National Museum Of African-American History & Culture, frames "whiteness" in an a way that is so detrimental and condescening to black people that I can barely believe it. But this formulation is being pushed by black people.

So it seems that we broadly agree on a lot of points. Which leaves me a little baffled by the claim that the article is "wrong on all counts and full of false equivalencies".

I didn't say anything about Europe or the Bosnians or the Irish or legal definitions of being white. So why do you begin by talking about them? What is it you're actually disagreeing with about the article?
