Yeah, those are all true. It's also not an open and shut case for films either - if a director consistently made films with antisemitic attitudes, questions would probably be asked about that director. Similarly, people have in the past questioned Quentin Tarantino's very frequent use of the word 'nigger' - though I personally think it's a stylistic choice than a racist one.

At the same time, no one is suggesting Matthew Weiner is a mysoginist because of his portrayal of men and women in Mad Men.
