@farah I mean, all you're saying is "sexism exists." And I dunno how relevant that point is to this discussion.
Biden, a white irish guy, ran on the same platform and was polling WAY WORSE than Harris finished.
So if sexism was a deciding factor, we could have expect her to do worse than Biden was polling, and Trump to significantly increase his voter numbers.
Neither of those things happened.
So, no I don't think it can be both. Sexism exists. It's not WHY she lost.
