L think it all depends on the mother that these men had growing up.
Why just the Mother though? I think husbands and Dads are equally responsible for teaching their children to be independent and clean their own shit away. If a Dad /husband is happy to sit around and be waited on by his wife then he's equally to blame if his son grows up expecting the same from women when he's also an adult. He's also equally responsible if his daughters grow up assuming it's their job to pick up after grown men as he's modelled that very behaviour too.
If we say it depends how the Mother is, there's an underlying assumption that raising dc and the imposing certain values for adulthood is the job of the woman. The very thing people on this thread are arguing against.
Nagging is used as insult to a person (often a woman) by the person (often a man) being asked to pitch in and do their share, because the person being asked doesn't want to it or thinks it shouldn't be their job.
I also believe men's eyesight can see dirt just as much a woman can, just that some men don't think certain things should be for them to do and therefore don't like being asked and probably hope calling the person asking a nag will stop them asking and that they'll pick up for them.
DH is often told he's 'under the thumb' if something comes out that he's done at home, he works on building sites so heavily male dominated, few weeks ago dh sandwich hadn't been cut in half properly and some of his filling fell out, a few of them told him to "get her told" and got a load of henpecked etc insults for making his own sarnies, he just replies "better than being the type of pathetic cunt who can't make a sandwich"
