This is the heart of our predicament. The Left is at war with reality. They think it's optional.
Its because what the left advocates in politics is actually their religion!
The left always denies empirical reality and lives in a utopian fantasyland. The odd thing is about half of the people mature out of that immature thinking when the reality of making a living smacks them on the side of the head. But half remain mired in their dreamworlds for their entire lives.
