Is it that hard to understand that someone might be in favor of something in principle, but object to its particular implementation? Or that someone could act against their own self-interest because of a belief in a broader principle? Maybe everyone's motivation isn't to blindly follow their own micro-self-interest.
Any time I hear the claim that people are against their best interests it does not quite make sense to me. My own observation leads me to believe that everyone is good at optimizing for their own priorities.
