Not meaning to re-ignite this powder keg (not that there's anything wrong with that), but yesterday's "Thought for Today" in my local newspaper was apt for this thread on both sides of the issue:

"If there is any principle of the Constitution that more imperatively calls for attachment than any other, it is the principle of free thought---not free thought for those who agree with us but freedom for the thought that we hate."

---Oliver Wendell Holmes, Jr. (1841-1935)
