The clear problem of the outlawing of insult is that too many things can be interpreted as such. Criticism, ridicule, sarcasm, merely stating an alternative point of view to the orthodoxy, can be interpreted as insult.
I believe in the soul. . . the small of a woman's back, the hanging curveball, high fiber, good scotch, that the novels of Susan Sontag are self-indulgent, overrated crap. I believe Lee Harvey Oswald acted alone. I believe there ought to be a constitutional amendment outlawing Astroturf and the designated hitter. I believe in the sweet spot, soft-core pornography, opening your presents Christmas morning rather than Christmas Eve, and I believe in long, slow, deep, soft, wet kisses that last three days.
People who talk of outlawing the atomic bomb are mistaken - what needs to be outlawed is war.
