*sigh* You made me actually have to go lookup these random crap talking points. God, these look like they are from that crap source Media Matters no less...
First one is a quote discussing not doing a prisoner swap for a marine but instead doing one for a WNBA player that got herself into trouble. He listed what the leftists thought were the salient characteristics (with the marine obviously being worth less). Sorry, I don't see discrimination there, other than the really old school definition where you can tell your ass from a hole in the ground.
The second one I can't find the video of but I dislike it because the frequency is overstated however exaggeration has been the name of the game for quite a while now. That being said without context I can only presume we are talking about things like the knockout game and we do know that has some racial targeting (although I would say Asian is also quite targeted). Sorry, its not raciest to tell the truth and there would need to be greater context to know.
The third one in context is just like the GP and the expanded quote says that he hates that by constantly pushing quotas and affirmative action when you hit these situations you have to wonder about the competency of the other individual because it is known that they are not promoting for competency above all else. Almost exactly like when encountering a nepo-baby or what I expect 75 years ago looked like in the south (with reversed races).
The last one is interesting and I am at least glad you quoted the right one not the one that says "all black women" as that one is a straight up slander from what I can tell. The context is that these are four women that came out and said that affirmative action is the reason for them getting where they are, so the list is perfectly rational. The idea that they think its racist for him to say it but not them is a telling point. I think the "white person's slot" is over blown as statistics say that it would probably have been two Asians and two Whites if it was by merit (probably 3:1 today). So, the only thing left is the brainpower part which is impossible to judge from out here. If you start with the idea that this is all a race hustle then it looks pretty true. If you think they are just your ideological gods then its false. In neither case does it seem racist.
So, as has probably been told to you innumerable times over the last 20 years, the definition of racist isn't that it disagrees with your sacred cows.
