>namely through the form of theatre
Classical theatre wasn't just like going to a pantomime or seeing some high-drama like Hamlet or Hedda Gabler or whatever. To use a modern parallel, it would be more like going to a modern cinema or video games to see or play some heavily sexualised, violent schlock which fundamentally served no prupose other than to titilate or gratify the viewers.
I mean this also in the sense that when actors on stage performed sex scenes, they actually did strip off and simulate the act to the point where it seemed like they were actually having sex on stage.
Plus, like today, the actors and artists were incredibly degenerate and prone to things like sodomy and cross-dressing and celebrity culture was every bit as poisonous then as it is now.
Having fun is not off limits. Entertainment is not off limits. Just know what kind of fun is.
