I think I am a bit more liberal than most in the Catholic community. I do ask questions and by the questions they seem to understand that I see things differently. They are not as confrontational as some commentators here. I ask people of other faiths and of no faith. I learn from other people. It is informal. There are not many people interested in discussing Einstein. 
On the Daily Catholic Mass, you may have seen Father Dan Donovan. He is very thoughtful and kind. He is a Professor Emeritus of Theology at the University of Toronto.
