Is "Kill All Men" toxic or not?

Anonymous
I know it's not mean to be taken literally, but is it really a "catch-all" flawless phrase that accurately pin points sexist men with no refused for female rights and gender equality?

I hear many things such as:
"it's a joke, if you're offended you're part of the problem",
"Women say that to vent, let them has this",
Or even "so what who needs men anyway".

The best way of handling hearing this is as a male who is trying his best to be an ally, is to just ignore it, but I can't help but draw parallels since if a man says anything like that about women, I'm supposed to stick up for them.

I know it's not a major issue or anything, but I can't help but feel like its a form of masculinity to tell men that if they're offended by hearing that, that their feelings are either invalid or toxic.

Please let me know if I'm missing something in my thought process, thanks.
