This is a movement of people mostly influenced by women (the priestesses).
There was a freedwoman called Hispala Fecenia, a noted courtesan...who gave a full account of the origin of the mysteries. "At first," she said, "those rites were performed by women. No man used to be admitted. They had three stated days in the year on which persons were initiated among the Bacchanalians, in the daytime. The matrons used to be appointed priestesses, in rotation. Paculla Minia, a Campanian, when priestess, made an alteration in every particular, as if by the direction of the gods.
These women encouraged the idea that there exists no kind of sexual or social more, and created their own counter-value that nothing should be unlawful (which is essentially what our SJWs mean when they misuse the word "toleration": they believe no kind of degeneracy should be even frowned upon).
The cult led towards further degeneration, including "men polluting one another" and men becoming effeminate.To think nothing unlawful was the grand maxim of their religion.
There were more frequent pollution of men with each other than with women.
And yet it would be less alarming if their evil courses had merely rendered them effeminate - that was in great measure their own personal disgrace - and if they had kept their hands from crime and their thoughts from evil purposes
In the first place, then, a great part of them are women, and they are the source of this evil thing; next, there are males, scarcely distinguishable from females.
But, please, tell us what Livy really meant.

We have our own analog to these people today. It's quite clear, Bjorn. Stop being such a massive faggot.
