Because I believe that in the long run principle beats selling out for expediency. Heck, just look at the GOP. They've been catering to sexists, racists, ignorance and wanna-be fascists for decades. No matter how politically unsound it was, they've consistently supported assault, rape, forced pregnancies, pedophilia, war crimes and countless other horrors, large and small. But when the time came, their voters turned out to support a senile reality TV star fraudster. What better example do you need that consistent principles win in the long run?
