If you wanted to use an actual one to attack the opposing tribe, you could go with some of the pro-life folks who plaster bumper stickers on their vehicles and talk a big game but appear to be bereft of much compassion for people in general. Those particular folks tend to trumpet their pro-life stance as a signal that they're good people.
I have my own issues with the gun fixation crowd but I've never gotten the sense that they promote unrestricted gun rights to trumpet their virtue and signal that they're better people.
The examples are so numerous on the other side of the political spectrum right now and so well-chronicled, that it's not worth the time listing all the phony stances taken to appear virtuous and feel superior to others.
