This is a fascinating document. I would love to read an accurate translation, the fractured English just gives the flavor. It looks to me that the text has been subjected to rigorous examination. The advances in thinking has made this branch of learning scientific with a computer program (named BAAL) analysing the vocabulary used and measuring the results being one of the tools. The people who have examined the material have used recognised methods of evaluation before reaching conclusions.
This judgement is not going to be easy to overturn. There is every reason to view the material as being at least anti-social. Having said all that, banning a religion is a big step. Voltaire said “Think for yourselves and let others enjoy the privilege to do so too”. That is the freedom we need.
