Entertainers used to be considered the scum of the earth. They were watched like hawks when around polite company. This can still be seen when the carnivals come to town each summer. No one really trusts carneys in their towns.
This changed for the most part with the creation of the film industry over 100 years ago. All of a sudden they became those one should emulate.
Because the silver screen is magic folks felt they could lower their guard.
We need to correct this mistake.
You missed perhaps the most salient point: during Elizabethan/Sshakesperian period actors and theater were quite popular, but regardless of the show, actors providing the entertainment were NEVER allowed to spend the night within the limits of the town or city.
The reasons why are as true and disgusting today as they were then.
