Some men just don't understand that when women explain why they don't like catcalling (because it makes them feel like, um, "cats" and not humans), they are actually not kidding.
Case in point: This dumbass who started catcalling girls during a video about how women hate and feel degraded by catcalling.
This guy might very well have the intelligence of a used condom, but I think he knew exactly what he was doing. Because when asked how he would summon a dog, he said he'd do it much the same way. Lovely.
So maybe saying some guys don't understand why it's cruel to catcall is a cop out. The truth is probably that guys just like claiming their dominance over women too much to admit that it's sh*tty.
