I have to beg to differ with you, but this is just from my personal experience, which may be diferent from yours. I've known lots of Catholics. Most are what what we call cafeteria Catholics. They pick and choose what rules to follow like food items behind the glass. It's a big country, so if you're going to characterize a religion, your mileage may vary. It's my understanding that one of the places where members take the Catholic dogma the least seriously is in Italy. I even saw an interview of a Vatican priest who thinks it's all a big joke. He may be looking for work.
Of course there is a connection between religion and politics. Conservatives tried to exploit it to win the Presidency. Mission failed.

Now I point out that religion contradicts reason because someone on this thread characterizes liberals as "feeling oriented" and conservatives as the rational type. Just pointing out an obvious inconsistency. For the last eight years, the true idealists, Bush, Rumsfeld, Cheney, Rice, Rove, Wolfowitz, you know the ones who thought the Iraqis would greet us as liberators? They were idealists, and they were Republicans, and they were
conservatives.
