Misandry is sadly extremely widespread and often not even recognized as a problem: Erin Pizzey who invented modern women’s shelters quickly found out that women were just as capable of being violent to their partners and logically tried to start men’s shelters as well.
What she had not expected was that instead with the support that she previously got with women’s shelters, the same did not happen with men’s shelters; instead she received insane amounts of hate, victim-blaming and death-threats from radical feminists. She had to repeatedly flee her countries because of material safety-concerns as a result of that.
In some way the peak I encountered of this kind of hate was some Fedi-site that had a rule banning misandry (good!), because it also harms trans people. Now the second part is very much true and as a trans girl I agree that it does and that that is bad, but that should not be the primary argument for why it is bad. That’s like saying anti-judaism is bad, because some Jews are white or saying misogyny is bad, because it also affects trans men or saying anti-black racism is bad, because it might affect white people with a strong tan: The statement is true and the secondary victim group fully preserves protection, but by making that statement you betray an incredibly bigoted mindset that doesn’t even respect the primary target-group enough to care about them at all.
There is a lot feminism that really just amounts to men-hating and that is why I do not use that label for myself. I believe in equivalent treatment and rights and so should everyone;
