Why would one think that? How exactly would input from men about women's feelings about men have any impact on the bonding experience between women about shitty male behavior?

If the point is to bond with other women, who cares what men think? It's not about them. It's more about no longer suffering them in silence.

Further, why would men even think they have the right or even want to intrude into that, other than once again, to usurp the narrative?
