"As being gay becomes more culturally acceptable, it will be interesting to see if gay vocations to priesthood and religious life decline, especially if the Catholic church continues to be perceived as a homophobic institution. Another 20-60 percent drop in vocations would be devastating to the church."

Vocations to the sisterhood declined as opportunities for women rose.  It is only logical to conclude that as opportunities for gays increase fewer will feel a need to resort to the priesthood.
