I'm a Southern Prod and have found Catholics to be more socially liberal than me but that's purely my observations.
Correct, if you look at the most Catholic states in the U.S. (Massachusetts, Rhode Island, Connecticut, New York, and New Jersey), you would notice that they are the most socially liberal in the country.
Don't let the other Freepers try to sell you on that line that these folks are CINOs. If that is the case, the majority of U.S. Catholics are CINOs.
Take it as you wish from a lapsed Catholic hedonist.
