"Irreverence is the champion of liberty." –Mark Twain
Free speech is the foundation on which all other liberties rest. Without having the right to express our opinions, however unpopular, those willing to use political clout, violence, and threats will stifle dissent, and we must all suffer the consequences of this. As George Bernard Shaw quipped, "Every great truth begins as a blasphemy."
"Society bends over backward to be accommodating to religious sensibilities but not to other kinds of sensibilities. If I say something offensive to religious people, I'll be universally censured, including by many atheists. But if I say something insulting about Democrats or Republicans or the Green Party, one is allowed to get away with that. Hiding behind the smoke screen of untouchability is something religions have been allowed to get away with for too long." – Richard Dawkins
