I personally don't see why condemning such a hateful ideology as Christianity is any worse than condemning other hateful ideologies like Stalinism, white supremacy, or fascism. Certainly Christianity has caused far more death and misanthropy than those three put together. It just has a lot more "true believers". Christianity teaches us that all the good things about mankind are the result of some divine entity to which we are all slaves, and all the negative things about mankind are the result of an innate wickedness everybody has from birth. This creates such a profound hatred for mankind that ridding the world of Christianity is absolutely imperative if this is ever to become a truly peaceful planet.
