You want to talk about his awful opinions, but you don't seem to have made any attempt to look past a little clipped quote to understand what he was actually saying. This is a classic way to create straw man arguments or twist meaning.
It's the exact sort of thing that comes out when people have real discussions, arguments, and debates.
It's why so many of the young people CK spoke to at universities didn't fare well in their discussions. They made a judgement based on some quote or phrase, without any context, and seemingly not even understanding why that would be important.
In your example, he was talking about how many on the left in the US think that standards for work and school should be based on racial status, with those in some given advantages, and others penalised. In a industry where that happens, you would not be able to know if members of the favoured groups had the same level of qualification as others.
It's not actually an argument that says that black people aren't as capable of being pilots as anyone else. In fact, you could argue that is true of the people who think you should reduce the requirements for black candidates - they obviously don't think they can get black pilots with the normal standard.
It's a very debatable position. He's used a kind of rhetorical technique to make his point stand out, and be a little edgy, but it doesn't tell us much about what he thinks of the inherent abilities of any race.
Similarly the earlier point about George Floyd - saying he's a scumbag might seem to speak ill of the dead, but if any other guy was described on FWR behaving like he did, he would get worse terms than scumbag used about him.
Why would people believe your other points when you haven't bothered to engage with these ones enough to understand them?
