Yes, I can see that all that is offensive. It also sounds like it could be pretty silly. I can't say without seeing it, obviously what's often shown has been 'selective' possibly to put it mildly.
One thing I do think is that it's always good to have rational discussions, and closing down discussion doesn't often achieve very much. Even if she did make such a film, it's still unclear to me how far she was fully committed to the ideas portrayed within it. Even if her work is in the end dreadful and beyond the pale I think it's good to analyse what has made it so, if only so we can recognise such tendencies in the future. Don't we have to look at the demons to understand them, and in particular understand their terrible power?
Anyway, the great thing about discussions is I'm now keen to go and find out more for myself......
