Peterson caught in a contradiction

In Overtime Peterson was talking about how liberals treat Dump voters as stupid, and that doing so was counterproductive. So Alex Wagner asks him about the contradiction, in that Peterson earlier said that liberals have to quit being politically correct and afraid of offending people. Wagner points out that Peterson is doing what he claims liberals are doing and she's right.

Peterson does though make a good point that if we get rid of Dump what happens to his supporters? What happens is that progressives will enact policies to help those people, like higher wages with better benefits, job retraining and a host of other humane policies. Progressives can still think these people are ignorant, even stupid, while simultaneously wanting to help them to get a good education to quit being ignorant and stupid so that they can be well-paid, constructive and informed citizens.
