Should we "dare" the Republicans in our lives to take political tests that might say they're a liberal?

Someone on this site said that they switched parties after taking a political test. I have talked to my Republican brother about doing it. He’s pretty liberal with social issues and is an atheist. I’m guessing he did take a test because he stated he thinks that the tests lean towards saying people are liberal. He is a life-long Republican who seems to be proud of it and thinks it makes him look “Upper Class” or something. I happen to think that Republicans have really crappy policies that most people disagree with and when they become aware of that, many people who have their heads screwed on right will start to question things.
