Im not sure I can agree with you there. There's a difference between dismissing it outright and dismissing it as an invalid argument on a case by case basis because it is being weaponized by an anti-feminist and/or anti-woman jerk.
In the example I gave, in order to determine whether the author who wrote that comment was someone who genuinely believes what he was saying or had some other agenda you had to examine his profile and peruse his catalog to grasp a baseline of who he is.
That is considering the argument's validity.
So how can it then be said to be dismissive?
That's a double standard. We don't hesitate to point out to fellow women (as feminists) when we think they're using the word misogyny wrong or applying it wrong. And if it was being weaponized deliberately for grievance or to detract from valid arguments, then we'd certainly comment on that and say so.
Also, while it is only one dynamic, it's certainly not a small one. Perhaps thanks to how the algorithm works, perhaps just bad luck, that IS the bulk of what I see in word use.
Most of the actual misandry I see never gets labeled as such. Misandry is also pernicious in a certsin way that misogyny is not. Misogyny has a 'stank' to it that's hard to miss. Misandry is often heralded by a siren call that men seem to enjoy. They never seem to see the trap and the hate in what is being laid out.
The TradWife movement is a good example. TrasWives hate men. There has to be some base level of "men exist to be used and serve women so women can live in leisure" thinking going on to be on that bandwagon. But a lot of men prefer that because it's veneer of respect and submission strokes their egos. They'll pair off with or chase after these women who hate men over a woman who wants to truly partner and then turn abusive online toward those women who would have been a partner to count on rather than a ball and chain weighing them down and scream misandry because onxe the money ran out, or his body broke down, so did she and now he can't see his kids more than twice a month.
When he agreed to that arrangement all along on all points. It wasn't something that just happened to him. He chose it over the better option deliberately. He chased after it. All for his overly inflated ego. It seems the masculine ego is the biggest man hater around.
And yes. It's also true that the feminine ego is the biggest woman hater around.
