"Tolerance was an Amercan Christian contribution to the world. Just as you drop a pebble into a pond, the ripples go out. There was tolerance first for Puritans, the Protestants, then Catholics, then Liberal Christians, and then it went out completely to the Jews. Then in the early 1900's, tolerance went out to anybody of any faith, monotheist or polytheist. Finally, within the last generation, tolerance went out to the atheist, the secular humanist and the anti-religious. And the last ones in the boat decided it was too crowded and decided to push the first ones out. So now you have a unique situation in America where everybody's tolerated except those ones that came up with the idea." - America's God and Country
Tolerance is a two-way street.
