Ex and I have talked at great length about all this since our son was born. She and I both saw a lot of the asshat males you talked of while we were growing up, and neither of us wanted our son to be like any of them. But in the end you can only teach them so much, and the rest is up to them to do as individuals.
Ironically, all this slanted me towards writing romantic themes in nearly everything I write, ahahaha. Strange world at times >_>
