Nevertheless, I understand the appeal of trying to change people's minds. I confess I still spend too much time trying to do it … as do Republicans and Democrats, Christians and Muslims, men and women, blacks and whites, etc.
Before trying to change someone else's mind, ask yourself this question: When was the last time I changed my mind?
P.S. Feel free to also ask this question to someone intent on changing your mind. If they can't document a meaningful area in their life where they have changed their mind, it is worth asking them why they think you should change yours.
