Hi Resolute Bandicoot and Terry - look at Pam's video (about the fist sign) then go to 3:06 of Resolute's video on the Frankfurt School. The fist is is the same one but with different colouring.

The idea of being forcibly shut up is like WTBS and it's concept of apostacy.
They mention Freud in the video Resolute Bandicoot put up. Here's a bit of extra info:-
Freud said to Einstein the greatest obstacle to the creation of a central organisation to secure peace lies in man's destructive instincts. Libido can be harnassed to counteract destructive instincts and bring about a superior class of independent and fearless intellectuals able to guide the masses into the path of reason.
Freud would accept no criticism of his methods, even justified doubts. Once again how similar to WTBS.
Thank you both for putting the link to that excellent video. It is very informative.
