BE what you wish to see reflected in the world. Love is made by being love. Peace is found only in being peace. See others as children. See how our collective being impacts them. What do you create? Love, Compassion, and Peace? Or Fear, War, and Hate?
Anti-Catholicism is the last respectable prejudice. You can't hate black people anymore, of course, and you can't hate homosexuals anymore, but you can hate all the Catholics you want.
