so yes men do get laughed at for this kinda stuff, by men and also by women. when men do it, i noticed it doesn't bother me as much truthfully.
i'll say when i'm in more women-friendly, radical feminist spaces (journals, magazines, irl events) there really isn't this negativity around. something like the scumm manifesto does say stuff that can be hurtful or seem hateful (i'd agree it is hateful; i'd also agree it's completely justified and rational given the circumstances) and honestly so much of the tension seems to me to be due to the online nature of this stuff.
are there women-only spaces where a bunch of negative things about men are said? obviously, and i can't for the life of me figure out why it's held to a different standard than other groups outside of the patriarchy being the explanation.
i think treating and seeing women as equal is accepting there are women who have awful takes. women as a group will be like many other groups, they might appear homogeneous and their's a wealth of differences between them.
i'm ok believing some men are toxic, as am i for some women, what i don't do is share that opinion with others if the circumstances aren't appropriate. i think that's where "think before you act" or "think before you talk" comes in.
i don't think it's ok for people to laugh at an abuse victim. i also don't think it is as important to work on at present compared to other issues. it's a shame it happens, and i think there are other battles to fight first; like boys for some reason (from the evidence from research i gathered) needing more like physical activity in schools and doing much better when they aren't tied to a desk all day. something like this is important, because testing indicates boys are getting worse especially recently in stuff like math and general literacy.
