There's nothing wrong with what is being said here. Except that there are just as many "climate" issues that woman and people of color have to face, if not more. This person is cherry-picking discussions about race and gender and saying "it's horrible that climate issues are making it difficult for these white/male students from participating" but the same level of outcry doesn't exist even though in almost every other field you can say the same kind of thing: "it's horrible that climate issues in computer science are making it difficult for these students of color" and the same people are silent.
And I realize I am doing a form of derailing right now, because the matter at hand is white boys being heard. But we're actually talking about white boys being heard during advanced discussions of race and gender. And honestly I feel a little bit the same about it that I feel about girls being heard during advanced discussions of parallel CPU architectures. I wish there were more women who were in those discussions, but I don't think the solution is "just let them participate even if what they say is totally ignorant".
Frankly, most white boys are not skilled enough to participate in discussions about race and gender. It's not that there's anything inherently wrong with them, the pipeline is just letting us down completely. Most of us get almost no education in race and gender, while girls and people of color get it for free just because of their gender or race.
The solution in my mind is the same as the solution to getting more women and other disenfranchised groups into computer science. Everyone just needs to take a little bit of responsibility for the part of the pipeline that's one step upstream from them. You can't just have boys who have never thought about what colonialism actually feels like diving right into university-level gender politics classes. But as a university professor I think you can support summer programs for teenage boys to help them do really basic level gender analysis stuff so that when they do get to college, they can actually participate meaningfully with the girls, and not be seen as second-class citizens just because they have less direct experience.
We shouldn't think of these boys as "bad gender theorists" we need to broaden our understanding of what gender theory is, and make sure we are creating opportunities for disenfranchised novices to get involved.
But this naive affirmative action approach OP is advocating, of "just make sure the boys participate equally" is not taking the problem seriously. Proper affirmative action requires you to get in and take responsibility for your recruitment process and the social issues surrounding it.
