Do none of you people arguing for the existence of misandry understand that “a woman was mean to me once” is not in any way remotely comparable to the systematic undervaluing of women as people for the benefit of men

They seriously don't. Like, they have no idea how it is out there. As a trans woman, i at least sorta kinda know both sides - i always completely sucked at being a guy and could rarely if ever actually enjoy the decidedly guyish parts of my pre-transition life, but i can still safely say that i know what it's like to have male privilege, to be the man in a straight relationship, to be able to hang out with the boys at / after work, to be your parents' son instead of their daughter, to be with the guys instead of the girls at a social gathering, to walk home at night when you're read as a dude vs walking home at night when you're read as a girl, and they just don't. And because they are the cultural default and their experiences are always the ones being centered, it stays that way. A huge part of how male suprematism works is that guys, average guys who aren't Andrew Tate and think of themselves as not being toxic douchbros, are still being completely oblivious to how different a woman's day to day life is from theirs. Most of them would not be able to make the same amount of use of women in their professional, private, sexual and emotional life if they understood how much we are still subjected to serve men in nowadays much more subtle, but still very noticeable ways. And if you point it out to them, if you point out that the difference between them and Andrew Tate is in most cases gradual, not absolute, they do everything in their power to reject that realization, because our servitude is so damn useful to them.
