Your framing is fundamentally illiberal. Refraining from engaging using “well deep in your heart” excuses means you can self-righteously ignore any position you disagree with and never have to face real argument. And it is wonderfully non-falsifiable, so you can always use it!
It is not "illiberal'. It is descriptive and objective. As opposed to pretending I am naive dumbo.
I did not engaged in "well deep down". I said "the motivation is clearly that. Even openly stated again and again and again whenever in front of symphatetic audience"
Those systems are not having disparate impats randomly. They were deaigned that way on purpose.
