The getting offended emotion seems to often be disproportionally strong. Even when it's not strong it's very often ill-fitting. In the service of ignorance and vanity instead of being against something actually harmful happening.
And then you can rarely even be sure if something causes any harm or not, or how much.
And then there's perceived dickishness of a filmmaker because of what happens in the film; should you be offended he's being a dick in the movies he makes, possibly away from real life, as long as the distinction is made clear?
