Born and raised Catholic. Although I'm no longer a participant in Catholicism, people often forget about the different branches of Christianity. Catholics once used to be hardcore on being strict and to the word of the Bible (Their Interputation at least). Now they are overall one of the most relaxed branches of Christianity. I personally don't know any Catholics who would deny Global Warming or Evolution (Hell I know some who don't give a flying f**k about gay marriage and lean heavily to the left). Although this can be skewed from my own opinion, but I do live in Chicago which is the Catholic center of the US and votes heavily democratic.
Yeah I went to Catholic school for 7 years and it was very interesting to find out how diverse and progressive Catholic thinking is these days. The head of our Biology department was a Benedictan Monk and taugh evolution as fact, while the school as a whole openly embraced LGBT sympathy. Then again, this was also in the liberal San Francisco Bay Area, so I think regional ideological tribalism is a much, MUCH more powerful method of keeping opinions homogenous than religion.
