It goes without saying we should bring boys up to be responsible and respectful, but how many do? How many even have a father figure of any kind in their live? They will seek one out, either online or in a street gang, and that 'father' may be teaching them all the wrong things but who even knows? Who can put them right.....
And what happens if the father is himself a bully and misogynist? Sons tend to use their fathers as role models. I've heard some boys show absolutely no respect to their mothers. Presumably, they then show other women the same lack of respect.
