Well, that should be fairly obvious, of course, but the cult has produced a number of rude, crude and obscene videos claiming to be from Anonymous. In fact, it is advisable to view all videos with care. It is nearly impossible to tell who has produced what. Certainly any material advocating violence on behalf of Anonymous has been produced to serve the purposes of the cult.
While it is possible that independent internet citizens could produce videos advocating violence on behalf of the cult against Anonymous, it is more likely that these really are threats by the cult since they have a history of unethical behavior that vastly exceeds anything that Anonymous has racked up in the last year or so.
Just keep in mind which group has plans to take over the world and subject all to its wacky will and which group advocates freedom of thought and freedom of speech.
By their fruits ye shall know them.
