There's more to this than the first ten posts touch on.
Mel is against nudity and obscenity.
Clean Flicks is run by non-Catholics and I'll bet you their edits maybe perceived and interpreted by Gibson as anti-Catholic.
I'll bet this comes out later on.
Mel would not want to shutdown a place that cleans up movies unless there is something else going on.
What would you edit out of the film to make it less Catholic? (and more Protestant)? They're clearly editing out the violence. And Gibson has been nude in quite a few films himself.
