Since the Bolshevik Revolution, the clenched fist has been the left’s most visible symbol. In the ‘60s, it adorned posters and buttons and was adopted as a symbol of revolution by SDS, the black power movement, feminists and other Trotsky wannabes here and abroad. Now, it’s been resurrected by some in Occupy Wall Street. The symbolism couldn’t be more fitting. Fists are for smashing (institutions and traditions), bashing (heads) and pounding (square pegs into round holes).
