That’s like saying it’s ok to call a stranger walking down the street who is black the n word. That’s just banter.Is misogyny not a bit strong for what might be perceived as bad behaviour.
Whatever reasons men might have, getting a laugh, to annoy the woman in question, etc for catcalling or what have you I don't think hating/disliking women is one of them for most men. If your man or anyone else wants a solution perhaps they should call it simply bad behaviour and explain women find it uncomfortable (in fairness you are going down this path) rather than going all hyperbolic with such terms as misogyny which leaves him with credibility issues and open to ridicule.
But if you’re working for Bus Eireann and refuse to let him on because he’s black, that’s racism,
Do unto others as you would have them do to you.
Empathy.
