Speaking only for myself and not large groups of people labeled progressives, I believe if we are honest we will recognize our very human inclination to first resist anything which opposes something we believe. Opening our minds to look from a different perspective on an opposing belief for common ground takes conscious effort. I’ve noticed how certain self identified political followers only “follow” those who share their zeal for the same candidate. In turn their information supply becomes a closed system. This is true in many social settings isn’t it?
