I'm not totally convinced the stiff upper lip stuff is really responsible for the issues men have with mental health.
Anyway, I don't know that I think statements like that are useful. Some men need to stop being asses. Some women have to stop being asses. Assholes need to stop being asses.
I can't do anything about female assholes and I don't want people to put that on my shoulders and I suspect nice men feel equally unable to do much about male assholes. What's Benedict doing about it, other than making statements like this?
