The way men are rallying around these boxers is very familiar. They are not being treated the way wronged females would be (forgotten, smeared, mocked, unheard), but with the softly-softly infantile approach commonly presented to men who believe they're women. There's a real sense of comradeship in the way they outright celebrate their "wins" against women.
I was wondering if brotherly love or woman-hate was their main driver, then I read Reddit (why do I never learn) and got my answer: "Hungarian lady talked shit, got smacked."
