To me, one of the most disturbing elements is the lack of appreciation for the virtue of temperance. There seems, often, to be an underlying assumption that genital pleasure is the One Unlimited Good, with every other good given only a tentative position.
For example, Msgr. Pope mentioned in a post about communion for people in irregular marriage situations that they have the option of sexual continence ... but he rarely finds anyone willing to give this serious consideration.
As for those who wold rather have illicit sexual union than Holy Communion --- they have certainly revealed the real identity of their one true god.
