Now... from the perspective of somone who has shot a wedding in every possible religious venue (except a mosque) I can tell you the following as truth based on my first hand experience.

Catholic priests are about 75% assholes.
Rabbi's and jews are completely wrapped up in their own misery. Move on people.
Baptists are showmen
Hindus are welcoming and appreciate outsiders
Sikhs are nice but there's a quiet racism there
Born again types are pretty damn cultish

The rest of them are generally the same

There are exceptions to all the above but that's pretty much my truth.
