WRONG! I open a bar (since you used the bar reference before) I standing behind the bar and talking to people who visit my bar. They like me I like them and we are having just typical chat seesions. Now someone with MY bar decides they do not like the conversation and got next door to say "Bad Mouth all you want" bar and gets someone or a crowd to suddenly invade MY bar to disrupt the atmosphere. I as the Bar will immediately toss them into the street and close the door behind them and resume conversation with people I like.
And there is nothing wrong with that.
If you opened a bar, you could not legally do this. You could only do this in your home. This is neither your home nor your bar.
