I evaluated it. I read the manifesto in its entirety.

He starts off by saying he's not against diversity, but then spends the rest of the paper demonstrating the exact opposite, and then justifies it by claiming that men and women are biologically different, and that a lack of diversity is ok because of that, or that any perceived discrimination is ok, because it's not really discrimination.

And he uses the issue of "dialog" as a smokescreen. It's the same kind of tactic used by creationists wanting to "teach the controversy." They don't really want to honestly debate the merits of each position.

This isn't dialog, nor does he want dialog. It's simply him trying to justify his prejudice, and railing at "PC culture" for not letting him do so.
