lol its poking fun of the douchebaggy way some guys will talk down to you about stuff you didn't ask to be explained about. Of course many women are just as condescending and arrogant with their explanations- but perhaps it comes off as extra tool-ish when a guy does it cuz men are naturally strong anyway. I'm sure I fagsplain a lot.
Toxic Masculinity... I dislike this term more than mansplaining, because its implying that masculinity itself is somehow toxic. But sure yeah men are often assholes. I know then the knee jerk reaction is to be like BUT SO ARE WOMEN!!!11 but.... I don't see what's so wrong about focusing on men being evil and talking bout when men are pricks. Its like we are talking about THIS right here, not that and you said yourself nobody is really equal anyway.
And nah, the way to correct unhealthy behaviors in males isn't dumb PC commercials or anything....
its more honest and humane to just say 'ehh men are often sadistic little douchebags' than make up some dumb PC phrase like 'Toxic Masculinity'. Of course there are women who are cruel cunts too (and again, not the point) but on average in my experience more men have been jerks than women so I see where they are coming from. For every 1 girl that was mean to me in high school, 15 boys were. Maybe some girls secretly laughed when the other boys picked on me lol, which would piss some guys off but ehhh to me its more respectable in a sense.
