Except that you call all whites racist.
You don't even understand the definition of racism so how the hell can you accuse someone of something that you can't even define?
If you will recall the definition of racism/racist includes the belief that one's own race is superior and others inferior. The following is the very definition of racism and is an excerpt from the reason that the state of Texas stipulated for it's leaving of the Union.
So when IM2 talks about the 200+ years of white affirmative action which is a analogy, not to be taken literally, this is from where it stems and the damage inflicted by this beginning has never come close to being undone even with all of the laws that have been passed because racist being racist will always find a way around them
She [the state of Texas] was received as a commonwealth holding, maintaining and protecting the institution known as negro slavery--the servitude of the African to the white race within her limits--a relation that had existed from the first settlement of her wilderness by the white race, and which her people intended should exist in all future time.

We hold as undeniable truths that the governments of the various States, and of the confederacy itself, were established exclusively by the ***white *** race, for themselves and their posterity; that the African race had no agency in their establishment; that they were rightfully held and regarded as an ***inferior*** and dependent race, and in that condition only could their existence in this country be rendered beneficial or tolerable.
That in this free government all ***white men*** are and of right ought to be entitled to equal civil and political rights; that the servitude of the African race, as existing in these States, is mutually beneficial to both bond and free, and is abundantly authorized and justified by the experience of mankind, and the revealed will of the Almighty Creator, as recognized by all Christian nations; while the destruction of the existing relations between the two races, as advocated by our sectional enemies, would bring inevitable calamities upon both and desolation upon the fifteen slave-holding states.
