No, actually they don't have that right. They have the same rights as everyone else, which are to say as they please within acceptable limits and at acceptable volume and thus possibly hear other people exercising those same rights. That is the tricky thing with rights. As far as anyone has commented everything he said was well within the acceptable rights people lazily call "freedom of speech" (I hesitate to even use the phrase in such contexts for fear of cheapening it). Possibly he was talking while a speaker was talking, which is rude but again does not infringe anyones rights and while that might result in an apology to the speaker or some staff that is pretty much as far as it should ever have gone, had people been mature. Your understanding of rights appears naive at best I'm afraid.
