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.
These days I really think it's just a total non issue. I haven't seen one of those comments in years. It was a 2010's liberal feminist slogan that ran in pretty equal balance/opposition to utterly rampant misogyny of the times.
If someone said it in front of me, if it was a friend I might discuss how I think it's needlessly antagonistic and makes an unnecessary/difficult hill that you're then forced to die on. If it was just some random, whatever, I probably don't care much for their opinion regardless.
