You have remained silent on 'prowling blacks' as you're too busy to look into that one, though you did find the time to dig up some evidence of Kirk's supposed good works.
The gay rights one was posted on this thread by someone, various stories of Kirk reaching out to black people in their careers* have been on MN threads and another popped up on my Instagram feed. I didn't seek them out.
(*This you dismissed as performative despite being done privately).
Anyway, I watched your favourite Kirk interview this afternoon with the "prowling blacks" comment. Then had to watch the "New York Karen" YouTube video that it referenced to make sense of it.
The language made me uncomfortable. The incident is seen through a very racial lens with every protagonist described as white hospital worker or black youth etc etc. Kirk lashes out against the word "Karen" which he sees as racist and misogynistic.
Interestingly here (as in other videos) he seems wary of being seen as racist "If I said ... I'd get accused of racism" appears in a few videos. He also worries here about people stoking a race war. He sees his political opponents of doing the things he is accused of doing.
He uses "prowling blacks" (twice IIRC) as a justification for the woman in the video being alarmed at being jostled by the young men. Clearly his argument would have been far more convincing without it. I can absolutely see why someone would call Kirk racist from watching the video.
My most charitable interpretation, which i know you will reject utterly, is that his meaning isn't inherently racist (he believed the "karen" was in the right, the young men were trying to stop her taking the bike she rented, and she was legitimately afraid) but his language was. If he had said, she was fearful because the area had a high rate of violence by groups of black youths, including crimes against women, it would have sounded very different.
