They're a product of their upbringing.
The older generation sure likes to condemn these metrosexual kids with no idea of how to be a man. But they're not so quick to condemn themselves for being too self absorbed to spend time with their kids, or condemn themselves and their friends for being philandering husbands that can't keep a marriage together.
I can tell you it is as often "philandering wives" that break up marriages. seen plenty of that, and they still get the kids. Courts don't care who's screwing whom. So pass the blame around.
