My apologies, I made a poor assumption.

That kind of behavior should result in being ejected from any (every) establishment.

You're exactly right: your safe space must be kept safe.

I mean, have the bar kick them out because they're groping people?

I've been groped by gay men in straight bars, I never said gay men shouldn't be allowed there. I never even tried to have any kicked out, just said I wasn't interested.

If you told them that and they kept doing it, you should have had them kicked out because even if they stopped doing it to you, they'd likely do it to someone else.

But loads of places don't let in obvious bachelor or bachelorette parties, that seems like a more level headed path.
