quoting the OP, do you mean this? ”I don't know if there's a statistic that shows that women in general are less intelligent than men, and if there is I'd say ‘what's the f***ing point?'"
How is he saying that womans ARE less intelligent than man? if anything he is saying that he doesn't know if there are studies and that if there are they don't matter. Wich is kinda true since "intelligence" is already a nebulous thing to measure.
I'm honestly asking you here, i've watched the video.
The problem to me with a statement like that is, that he doesn't condemn the thought. Talking about measuring intelligence across groups is a very sensitive thing, and one that is pretty much tied to racism and sexism. There is good reason to not go into that direction, yet here is PewDiePie going: well, he might be right, I don't know!
How about, don't make a video then if you don't know. If you yourself say you are not the person to discuss this issue, then why do it.
The whole thing makes no sense, outside of making some clickbait that conveniently falls within alt-right talking points, complete with a clearly sexist politician which he is pretty much defending.
"I understand what he is trying to say. He is not saying women should earn less, he is saying they are because of these reasons. I don't know if there are statistics that show that women in general are less intelligent then men."
That to me reads like a pretty clear defense of that line of thought. After that he goes into his own reasons. But he leaves the option open that those differences might be there instead of saying: this is clearly bullshit.
And then again, we should not ignore the other issues surrounding this video which show some troubling things around him.
