A woman who puts her man in front of her kids ought not be a parent again. If the state has to step in in order to make it so, even this libertarian can accept that.
If someone, anyone, even his mother had tried to drown my son, I would happily serve whatever term I was assigned for killing the person. And if I stood by and watched, doing nothing, I should expect the opprobrium of society; and that includes not being entrusted with children any more. After all, if I failed to protect my own flesh and blood, what claim might I have to be a good guardian?
