Racism is evil — there’s no argument about that, right? Right.
And it A=B and B=C, then A must equal C. Simple logic, right? Right.
Therefore, if all white people are racist and (as you say) know that they’re racist, logic demands that all white people are evil.
Is that what you wanted to say? Almost certainly not. But if all whites are (1) racist, and (2) know that they’re racist, then all white people are evil…and such a statement would be racist in and of itself.
There is a way to show that yes, most racism — and the most egregious racism — in the Western world is committed by whites…and if you’ll think about it, it’s right:
In any given nation, there will be one socioeconomically dominant demographic, whether tat demographic is racial, ethnic, or religious in nature. It is that demographic that will commit the most — and the most egregious — acts of racism or prejudice.
This explains why whites are the most racist in the Western world, why the Brahmins are the most racist in India, why the Han are the most racist in China, and so on.
That’s the why…unless, of course, one insists that all whites are evil.
