How else can one explain the Left's enchantment with Fidel Castro, the totalitarian ruler of Cuba? Clearly his evil is of little consequence. What matters to people on the Left is that there is free health care and almost universal literacy in Cuba. Whereas non-leftists believe that it is far better to be illiterate but free, leftists believe that it is better to be a literate slave.

 Today, this inability to either recognize or to hate evil is manifested in the liberal opposition to the war in Iraq. As I pointed out in a previous column, opponents of the war should be asked to at least acknowledge that America is fighting evil people and an evil doctrine in Iraq. But even that is difficult, if not impossible, for most people on the Left.

 As noted above, everyone hates someone, and that includes people on the Left. The problem is that because they don't hate evil, they hate those who oppose evil. That is how liberals went from anti-communist to anti-anti-communist. To paraphrase one of the greatest moral insights of the Talmud, those who show mercy to the cruel will be cruel to the merciful. So, George W. Bush, not the Islamic terror world, is the Left's villain; life-embracing Israel is the Left's villain, not their death-loving enemies; and religious Christians who note moral weaknesses within the Islamic world are the real danger, not the moral weaknesses within the Islamic world.

 To be fair, it should be noted that confusion over evil and insufficiently hating it are not confined to the Left. There are religious people who conflate sexual sin with evil and/or advocate automatic forgiveness of all evildoers, even when no repentance has taken place.

 But the inability to acknowledge the greatest evils, let alone to join in fighting them, is the defining characteristic of the Left. That is why former Vice President Al Gore just announced that global warming was a worse threat to humanity than terrorism. He really believes that. As do the great many people on the Left whose moral passion focuses more on gasoline prices, drug prices, health care prices, and other expressions of material inequality than on people and movements dedicated to murder. That is why Robert Redford and friends from Hollywood can celebrate Fidel Castro. Castro may imprison political opponents, and most Cubans may have no right of dissent, but they are economically equal.
