Burning books is rarely acceptable. Only Jewish filth and poison and pornography deserves to be burnt.

I think there are basically two paths for any civilization (terrestrial or not). They can become like angels/demigods, or they can choose to become demons. But that is only a description of their nature. For instance, some people are outright demonic, i.e. they behave like demons. It doesn't mean that they actually are demons.

And NS Germany was like a nation of demigods compared to the Negroes in Africa. I own some Hebrew texts that are a few centuries old, but am I going to burn them because they are written by Jews? Of course not!
