Does there exist any evidence for Camille Paglio’s statement:
“Everywhere in the world you find this pattern in ancient times: that as a culture begins to decline, you have an efflorescence of transgender phenomena. That is a symptom of cultural collapse.”
This shouldn't preclude another more comprehensive answer, but this argument is a close cousin to the well-worn homophobic canard that homosexuality caused the fall of Rome. That has been discussed on this subreddit many times, most recently here by /u/J-Force.
