I don't disagree with the first part, necessarily, but by the same token, I don't think what Biden said or is doing about it is beyond any pale. I think there was value, and not just political value, in making the promise to an historically underrepresented group of people, within which there are surely hundreds of candidates who qualify at least at the level of Clarence Thomas.
You see Biden's strategy here as a net negative, and that's your prerogative.
