Perhaps you haven't met enough Jesuits. The ones you hear about in the news tend to be the liberally outspoken ones. The vast majority are not. I was lucky enough to attend Jesuit HS & college. Some of the best, smartest, and most conservative men I've ever met are Jesuits.
Unfortunately, while Jesuits do take a vow of obedience to the Pope on matters of Church doctrine, the Society was formed to be apart from the Church on other intellectual issues.
I went to a Jesuit school and I know a lot of Jesuits. I had one Jesuit priest as a teacher who was a conservative. He has been dead for years. All of the others are to the left of 0bama.
