I hadn't seen this (I've seen the facebook page and BFI's useless response).
I'm in.
I don't see what the quality of his films has to do with it, and 'censorship' seems to me - sorry - a ridiculously OTT word to use.
No-one is, so far as I can see, suggesting his films should not be sold. But that is quite different from saying he should be publicly celebrated for them.
It's a bit like William Mayne's books, IMO: before I knew about him I read them, thought they were charming, and I wouldn't want to see them banned. But I would be pretty shocked if someone decided to do a great big celebration dedicated to him, unless they also acknowledged he was himself quite a deeply nasty person who abused children.
