I find it encouraging that a well known liberal is doing what his ideology says to do, present facts.   No bitter comments, no lack of respect for those who he might disagree with, an acceptance that the truth only happens is you allow diverse and contrary examination.     Nothing in what he wrote says, or implies, that a particular conservative ideology should be accepted as fact.    

The truth is neither liberal or conservative, it is simply the truth.    It's clear that people all along the spectrum, not just politicians, have hardened their belief's as if arming for battle.  

Put your weapons down, take off the armor, sit and talk with your neighbors.     Our comments will be better when our listening improves.
