What's politically correct is often both rude and ignorant. Just think of what views were PC about various ethnicities in Germany in the 30s. Of course nobody in power (or who wanted to be accepted by society) would say those views were rude or ignorant. It was only after politics changed that people would look back and call the formerly dominant ideology what it was. The question is, what beliefs does society currently enforce that are wrong? Don't answer publicly, since by definition there would be a serious social cost for you speaking what society doesn't want spoken. Or have we maybe outdone every preceding generation and actually managed to be right about every belief we hold dear?
