I can tell you some things about Good Men.
Good men never respond to comments about the prevalence of male violence with "Not All Men Are Like That". They understand words, they understand logic; they know that many or most is not all.
Good men never take comments on the prevalence of male violence as attacks on their masculinity. Their masculinity is not contingent on being a violent male.
When women talk about male crimes against women, good men never assume this means the women hate men. They might, however, express surprise that more women don't hate men.
Good men never say "But women do it too". They know that a miniscule number of women might be ultra-violent, and that this is no argument against the avalanche of ultra-violent men.
When talking about crimes of sexual violence, good men know that these are overwhelmingly male crimes.
Good men don't make jokes about sexual violence. They criticise such jokes, the same as they criticise men making sexually degrading remarks about women. Their friendships are not contingent on being a sexual predator.
When considering the prevalence of male violence, good men are aware that its victims are most often men. They realise the problem is violent men, they don't blame women.
They see the ubiquity of violent men and sexual predators as a serious problem. They might not know what to do about it, but good men never assume it's just something we should all learn to live with.
Some good men and women can fight if necessary. A person's capacity for violence is not the problem, but good men are not aggressors.
Good men are rather thin on the ground.
