I can’t answer this question because I do not proclaim to speak for my god, I can only presume according to history and myth. Foremost, the theatre is of importance to Dionysos. Naturally, this is related to free speech and expression. I believe that hindrance of these concepts (censorship) is something that is close to Dionysos. Speech is hurtful, it is harmful, it is painful, it is powerful. Yes. But to silence this speech to cater to others bios feelings is wrong. Painful words are liberating.
“And its apparent capacity for human speech transcends the boundary between human and animal, and so makes it one of the creatures attracted by the singing of Orpheus.” (Seaford, 2006, P. 65)
With speech we transcend boundaries and relate directly with Dionysos. We can create worlds, we can offend crowds, we cause emotion and feeling with a single word. This is power and something that is not just granted to kings, fools, or priests but to the mob. This is equalising and liberating. When we’re faced with such hardships it’s the theatre that liberates our tongues and speaks out to our perceived injustice. Speech allows us to empathise, understand and when it doesn’t, it give us platform of protest and rebuke.
Thus, if I presume a cultural issue at heart of Dionysos it would be free speech.
