Our parents and their parents all tried to conform to a type of idyllic family stereotype that was never attainable. Family members were ignored and ostracized for behaving outside that stereotype. Excuses like "it's a fad" started specifically because of the need to explain away the behavior without allowing any follow up questions.
It took a long time but we are finally able to embrace our differences and recognize what's actually normal. Conservatives are still fighting to live that unattainable lifestyle and mad at everyone else cause they can't.
And could you imagine what that does to you mentally? Trying to square the circle? I'd imagine people that subscribe to that ideal have vastly higher domestic abuse rates. As long as they aren't murdering small animals and hurting other people, your kids and family are growing fine.
