Seriously, as I told a well-meaning Catholic layman who thought priestesses wouldn't be such a bad idea, it's a package deal. You allow the ordination of women, and all the other stuff comes in the door as well.
Amusing point: he was praising a local Episcopal female priest as a "good person" and so forth . . . I asked if he knew that she had left her parish here, been promoted to an administrative position in ECUSA, and had LED the ECUSA contingent, complete with banner, in the pro-abortion march on Washington this summer.
He did NOT know that. Sort of took him aback. (She was always a loony feminist crusader type . . . "goddess worship" and New Age crud abounded at her (small) parish.
