Because for years, people could be as shitty to "men" as a general category as they wanted to be, and no one was allowed to call it out. Anyone who did try to call it out got labeled as a right-winger or a misogynist or a redpilled men's lib chud.
People literally started saying "misandry" is a misogynistic dogwhistle. As if calling out shittiness and hate implies that you're actually peddling shittiness and hate for the other.
Maybe for someone who believes the only way to combat hate is with hate, then calling out hate might be seen as hateful. But if that's the case, then it reduces life to a zero-sum game, and if that's the case then it's anything goes, survival of the fittest. I for one don't believe in such a bleak vision of the world.
But for years any attempt to call out misandry was met with vitriol, usually proving the point but no one seemed to see that.
I've been saying for years that these double-standards are toxic and destructive. I've been destroyed on reddit multiple times for it, back before I got permabanned. I've had multiple arguments over it here too, and people just dismiss me as "sexist" for it, even though they're the ones being sexist.
So honestly, it's kinda nice to see a post that says, subtextually, "What this person said is very shitty" when showing a misandrist tweet. And it's nice to see people agree that it's shitty.
It feels like the world is waking up a little, like it might finally be ready to look itself in the mirror and realize that no hate is excusable.
