I want to add that I think that all three of these options are legitimate enough to consider, and I think that there are people who follow all of them. I don't always succeed, but I feel a moral push and try very hard to live my life using strategy 2, at least in situations that allow for an actual debate between the sides. However, I know people who I believe would say they think everyone should follow strategy 1, and I think that that most people follow strategy 3 most of the time without thinking about it at all.
