So I'm sure a fair number of men who were teenagers around 2015 went through that alt right pipeline. The gamergate crap, youtube "skeptic community", "mens right" and the like. I've been there, unfortunately.
I've gotten over the most of it in a year or two afterwards and come agree with the stuff I've dismissed since. (Mostly as a result of hate watching "the other side" and their arguments sticking) But I never really got over slogans like "kill all men", "abolish men" being said by women, always made me felt like I'm being unfairly included in the group and it's unhelpful campism. Hell I even ranted about it on Hexbear once. (cringe rambling alert).
Slogans like that isn't really seen anymore post ~2018, until recently someone randomly brought it up on a 
thread. One person just replied
It's basically the equivalent of "Another kkkrakkka down unlimited genocide on the first world". 
And that ticked with me instantly. I'm no 
. I'm not from the first world. I'm in "the other camp" and I post stuff like that. But I don't actually mean I celebrate people's death as long as they are white and want to genocide the first world, it's just a statement against imperialism, just like "kill all men" is a statement against the patriarchy.
That's all the rambling I got today. Hopefully if there's anyone here with similar thoughts, this can help them get over it too.
Okay I bet someone is going to tell me the objective of feminism is to actually kill all men now.
Metaphorically we could argue that we need to kill the "man" inside all cis men, meaning deleting all the internalised patriarchal education.
further explaining
Some would say "but there are good things about masculinity! Like being strong and stuff!" but if a genuinely good thing is associated with masculinity then it's something patriarchy stole to non-masc people and they should to take it back. Physical strength is cool and good, women are stigmatized for getting stronger because physical strength is associated with masculinity, so we need to end this and let women get stronger. Cismasculinity should be defined as everything wrong with the cis men demographic, because everything that is right isn't to be gatekept by them.In that sense, yes the man inside is to be killed, which doesn't mean all cis men should stop being strong, they will simply stop being seen as comparatively stronger as non-masc people catch up on that field
Typing my rant I realise I have a blind spot about trans men and how they express masculinity so if anyone is willing to provide their perspective that would be great!
