Really... you don't see the difference between a university scheduling a person to speak to students and is subsequently surrounded by idiots screaming "C***!" to a couple guys having trouble hearing each other in a bar?
Seriously?
Oh, I see the difference. What I am saying is that the difference is without distinction in this topic.
The one situation does not create more right to freedom of speech than the other. You really cannot comprehend the nuance I am underlining? You really think we live in a world where the only people that deserve freedom of speech are the ones giving lectures in classrooms?
Flip it around. Let us say you are right, and the people in the bar do not have as much right to speak. Fine, now anyone who talks about pro-life matters in a bar will be kicked out. It is not like a bar is a classroom, so what does it matter?
Well, maybe I am misunderstanding you. Maybe for you the distinction is the content of the conversation. Then it is ten times worse what you are suggesting: content based determinations for when someone has freedom of speech. So certain predetermined subject matters are deserving protection and some are not?
No, anyway you slice it, it is absurd. Interrupting someone is rude and that is all. It is not an abridgement of their freedom of speech.
