Here's an interesting article from Religion Dispatches about Michael Moore's faith background:

http://www.religiondispatches.org/blog/mediaculture/1889/are_michael_moore%E2%80%99s_films_inspired_by_his_catholicism/

I have  never seen any of his movies (yet) and so I find it impossible to have an opinion

I have no doubt that Michael Moore is inspired by his faith. But we then really have to ask, "faith in what"  - my bleief is that he has faith in common sense and has to use chaotic means to unleash some.

I really, really don't like his movies.  In fact, I hate them.  He seems to love innuendo and guilt by association.  His "theories" are often ridiculously simplistic.

However, I love his politics.  In every interview I have ever seen with him, he shows himself to be a passionate spokesperson for the underclass and the powerless.  He should run for office.

Just saw capitalism and he is very clear about his christian faith as source for his politics
