As a point of general information, when I refer to "Science" in a religion debate, I don't mean what we typically call science. I mean the Holy Apostolic Ecumenical Church of Science, populated with all sorts of people who have generally rejected religion and replaced it with any number of causes, like anti-GMO, anti-"toxins", the evil of gluten, juice-cleanses, etc.

Ask a Catholic priest how he feels about people who are in favor of gay marriage. Ask one of the people I described how they feel about people who are against it. Compare their hatred of the other side.
