I think its in response to incels like Eliot Rodgers gaining media prominence by going on shooting sprees and mass van killings. I've also seen rhetoric like yours being repeated everywhere, it's on Facebook and Twitter and Instagram and all the other places normie women frequent, usually thanks to MGTOW spergs.
I mean, it's good feminist propaganda. All they have to do is grab random screencaps of guys sperging tf out and post it to a Facebook group full of vulnerable 20somethings and it just reinforces the feminist world view: that men hate women and want to hurt them.
Like I've said, there are entire threads on KF archiving the autismal sperging of people like this. That's why seeing it is so frustrating for me because its just endless rounds of white guys shooting themselves in the foot and not understanding why they're bleeding.
