Keep your day job.
Free speech is meaningless if anyone who disagrees can shout it down. THAT way is the way of Fascist and Communist bully boys. It's not the way the free discussion of ideas is conducted in a free society. If you don't understand that your elevator doesn't go all the way to the top.
Let a speaker hold a crowd by his speech, and not jailing those who dissent. In meetings a more regular order is desired than a political speech -- and this was a political speech by Mr. Bush, even though he is the President. So in meetings there is less tolerance of repeated and vociferous speaking out or noising off -- but even in regular meetings some allowance for same should be made. That is if one understands freedom, respects the the minority opinion, and loves Liberty.
But there are some, and in history many, who seek a King that must be heard by all even by force, who desire a Nobility so that crass and discordant opinions may never appear in any public venue.
Those folks -- by the way -- when they are on elevators, sometimes get tips. But generally they are ignored.
