A few don't factor-in whether they stand alone when measuring good & evil. The remaining majority offer popularity as factual evidence of good, as you have done here.
Holding principle over convenience does not obligate applause from others. Neither does it warrant ridicule, especially from those safely flocking with the popular.
If the approval of, or membership in the herd carries no import with my judgements; do you really think ridicule will raise any self-doubt, or make your party more attractive? Is there any reason in support of your party, or does reason only provide shameing those that don't.
As both practice this same strategy, I have to ask; are you a Republican or Democrat.
