“And it demonstrates one of the reasons why the Roman Catholic Church (wisely or not) originally went for priestly celibacy: too many offspring who are entitled and undisciplined when the clergy are married.”
Sexual misconduct will always manifest itself one way or the other, as it has in the celibate priesthood in the Catholic church having a history of homosexual relationships rather than heterosexual ones. Limit heterosexual and you will get homosexual behavior. Let he who is without sin cast the first stone.
Yet, with a general decay of standards, there were also more than a few episodes of heterosexual priests who strayed. I believe that some were even deliberately protected by the "gay mafia" as way to divert attention from their broad and systemic misconduct.
Although little known, there are validly married Catholic priests in the US and worldwide in the several Eastern Rite Catholic Churches that acknowledge the Pope's authority. The most sensible resolution for the issue to me seems to be to keep priestly celibacy in general but establish a separate Roman Catholic ordinate of married priests under rules similar to those applied by the Eastern Rite Catholic Churches.
