From Wendy Kaminer:
Death, disease, war and genocide are tragic; famine is tragic; climate change is potentially tragic. An isolated incident of anti-Semitic graffiti is unsettling and lamentable, but it is hardly a tragedy. It is human nature. Few of us will go through life without being insulted or disliked on account of race, religion, sex, sexual orientation, or other immutable characteristics. People can be mean and stupid. People harbour biases; they always have and always will, and their right to believe in the inferiority or sinfulness of particular groups is the same as your right to believe in equality.
America's, and for that matter the world's, increasing obsession with purity bugs me. It kills debate with self-righteousness and the idea that being right affords one the right to be ignorant, intolerant, and obnoxious.
