Exactly. His message of "maybe be nice to the people around you" is nice when you remove it from context and ignore everything else he says. He made it explicitly clear that he was here not to abolish but to fulfill every last law, which includes every disgusting, outdated law "progressive" Christians ignore. The rise of Christianity represents a shift in economic systems, from slavery to feudalism. Feudalism is very much something we must strive against, and we should not be looking to feudal philosophies and religions for guidance, especially not for a socialist future. We must look forwards, not backwards.
As someone from a very religious, Christian background, I find it very frustrating that leftists cling to it so dearly. I lived real Christianity and there was nothing leftist about it. We must be careful, of course, to separate religious structures from religious proletariat, but we cannot tolerate the existence of religious structures. We must strive against religion.
It also explicitly condones and commands the murder and mass rape of women, the murder of gay people, the murder of people who work on weekends, and the murder of people from other religions, and on and on. The Bible is a barbaric book, and Christians aren't at all better than any of the cultures they accuse of barbarism for doing the same things they do.
