A really large proportion of the political class—and, I think, more of them, the higher up you go—are basically practicing kayfabe (the façade of reality that "Pro Wrestlers" and many fans engage in). They rip into each other on TV then go golfing together like nothing happened, same as a wrestling "face" and "heel" in the locker room might be cordial to one another when the cameras aren't following them. None of it's real, just an act, for lots of them, including the policies they push.

No its very different. Politicians gain considerable power and individual benefits from lying and being hypocritical.

Its hard to argue the same for gay priests who only occasionally get laid as a result of their choices.

If one genuinely believes in a religion, then being a priest is presumably one of the most beneficial careers imaginable. I wouldn't preclude somebody being both a homosexual and a genuine believer. One could even view it as a means of trying to atone, from their perspective.

This could be the same reason you so often see things like male sex predators seem overrepresented in e.g. feminist groups. The knee-jerk cynical view is that they're just their to prey on the women, but a more empathetic view might be that they are genuinely trying to atone for their inclining.

But in the end, we all are who we are.
