Or this could have the opposite effect: Unsteady Catholics may abandon the Church, but the faithful will remain. Judging by the homosexual lifestyle, I doubt that a lot of them will start showning up at Mass just because the priest promised to try not to make fun of them. In 30+ years I have never once heard a priest go out of his way to insult gays.
This whole issue is a giant red herring to get the bishops off the hook. They're just plain scared to be real bishops and protect their flock from the ravening wolves.
They'll know what it means to be really scared when they finally give an accounting to God for their negligence.
