You have to admire the Left for its clarity of vision. It has identified its enemies, and it does what it can to drive them from the field. The recent fireworks in Indiana are a perfect illustration. Team blue knows that Christians are hateful homophobes, and so it goes to bat for the right of homosexuals to sue them over wedding cakes. The Right, with its characteristic acumen, mistakes this bushwhack for a principled stand. “Ah!” they say, “But if you support the right of a gay man to force a Christian to make a cake then you must support the right of the KKK to force a black baker to make a cake!” The average liberal couldn’t imagine a more irrelevant rejoinder. They aren’t making any such proposition at all. In their calculus, Christians (of the Not-fans-of-Pope-Francis type at least) are the bad guys and thus their interests are hateful and invalid and must be opposed. The KKK are bad guys and thus their actions are hateful and invalid and must be opposed. You attack bad guys. You don’t attack good guys. Whence the confusion?
The fact that they have such a clearly defined enemy is, incidentally, why the Left can mobilize effectively despite being a creaky, Frankenstein mass of mostly incompatible interest groups. Mexicans will ethnically cleanse blacks when their territories run afoul of one another, but they both vote for the same party. Homosexuals don’t always enjoy the gentlest of treatment from their Muslim friends, but they nevertheless routinely support Democratic politicians who promise more immigrants and “refugee resettlements” from all the vibrant corners of Africa and the Middle East. The Democrat coalition is organized not around a coherent vision of the future but a shared opponent.
