1. Okay
2. P.C. garbage in defiance of incontrovertible genetic research results and common sense and the simple reality before everyone's eyes.
3. Philosophy 101 teaches otherwise. Disparate results -- your point #1 -- don't prove disparate opportunity. The existence of x doesn't prove the existence of y unless y is the only possible cause of x; "systemic racism" is not the only possible cause of extant gaps between Whites and blacks. If x ("racism") acts on a, b, c, d, and e (such as blacks, Orientals, jews, Arabs, Hispanics) and a reacts differently than the others, there must be something distinct inherent to a. If a given quantity of X ("systemic racism") produces a given quantity of Y (such as black crime rates) then a reduction in the quantity of X (undeniable reduction in racist attitudes + legal mechanisms to diminish race-based practice) will gradually cause a reduction in Y, which hasn't happened. Asserting that, because x would produce y and y exists, x must exist is fundamentally fallacious.
Did you read the 2nd article I linked? It's quite objective & even-handed.
It's always about the narrative that advances the agenda, never about objective facts. If objective facts and the conclusions to which they inevitably lead were the only considerations, "racism" wouldn't even be a thing
