This is the thing. Most of America is in the same boat with their "Christianity" it's just a bit more veneered. Christianity is largely a cultural perspective and not really one that is about the teachings of Jesus. This is how you get pro-war, white supremacist, evangelicals. The culture is the Christianity, not Jesus. But holding onto the facade allows you to hide behind the goodness of Jesus as something that's an inherent value to your culture. So you can say ... bomb Muslims, say of course Jesus wants you to not, but we live in a fallen world and that why we need Jesus. That's way more culturally palpable than saying "I hate brown people and I don't really care." One allows you to believe you are still fundamentally good. It disconnects your motivations and actions.
