One might assume these men are already these type of men. If so, they need to have a talk early about how men treat women and how important it is that a woman is treasured. If they aren't those type of men, they should be avoided.
Furthermore, in another thread about all boys schools, they talked about how boys are more focused, goal oriented, and successful than at public co-ed schools. Find your sons role models that you want them to emulate they can be coaches, mentors, pastors, etc. it's up to us to build our sons into respectable men,rather than let them be what society wants them to be.
And most importantly talk to them about being me of honor. What does a man do as opposed to someone with no class. Raise him to open does, assist women, carry groceries, help women in the neighborhood, etc. Tell that a man always pays. Tell them that a man provides.
I know a lot of women believe that they have no influence of how their sons relate to women, but I believe that is wrong. Mothers are the strongest influence in a man's life. The reason why the 19th amendment (Woman's right to vote) was passed was because the deciding voter, who was initially against it, was told by his mother to vote for it.
No one will ever make me believe that I cannot influence my son to make good decisions.
