It is nice to have places reserved for lots of things. So, I am not stating that these things should not be allowed to exist.

I will assert that places which don't teach the younger generations to interact in them, and instead forbid them from being there, are doing themselves a disservice.

But if there are "quiet hours" or "adult swim" times, that makes sense. All the more so when there are kids around to see how that operates. :D
