I perceive the "It's okay to be white" slogan as a very moderate and constructive reaction to the propagation and even normalization of anti-white messages and memes. And I specifically mean anti-white as an ethnic hatred, not as part of an equality and justice argument. For example, see the "Karen" meme, which besides its horrible sexism, specifically focuses on white women.

Middle-class white people have increasingly witnessed a media and a left-wing political coalition that can vilify them with impunity for gain, be that entertainment value or the easy political cohesion that hate can generate. So, I'd argue it's important to make room for and accept the very tepid and nonthreatening "It's okay to be white." Because if we don't, what follows that will be less palatable.
