I know what you mean, and I don't think you're over analyzing. I assumed the same. It also makes them feel less guilty about facing the social judgement that comes with the territory. Just like the current US President who is all "Family Values" with a host of hookers, ties to a pedophile ring (even appointing the fixer attorney to the White House for a while), 3 marriages all started with affairs, children with 3 different women, was cheating with Stormy Daniels while his current wife was pregnant with their kid, constantly lying, etc.... They have to lean far in the opposite direction to make themselves feel centered.
Then there is the whole education and personal achievement, but I'll just leave that there. It's very common and disturbing.
