As for women priests, that would indicate approval for same-sex marriage - lesbianism in this case - because theologically the Bride of Christ is the Church therefore priests, as alter Christus, are married to the Church. If women are priests they would be married to the Church which would indicate lesbianism.
Additionally, married men and women as priests would indicate approval of polygamy since a priest as a married man would be married to his wife and to the Church. And a woman priest married to a man and to the Church, or a woman priest married to another woman and the Church, would indicate approval of poly fidelity.
Furthermore, transgender people would be in an uproar to get equal rights to the Priesthood of Christ. A transgender woman would really be a male priest; a transgender man, who is really a woman, married to a lesbian could be a priest. The result of that would be to remake the Bride of Christ into a gender neutral entity so that no parties would be offended by the Church being cisgender.
In addition, all of this would mean that the laity would likewise be able to participate in such unions.
Wouldn't it be better to leave the Priesthood as Christ founded it?
