This is, I believe, not possible.
Our media has every incentive to carve out a demographic and get them angry at others. We have a winner-take-all political system with two political parties, which creates polar arguments. Duvarger's Law makes fixing this impossible.
And I think you have the wrong impression of what these are. They are very limited, but the newspaper story doesn't go into those rules. It's a way to remove differences so that one group, say people who believe Obama is the Anti-Christ, can try to achieve something for themselves free from those of us who prefer reason. In any peace process, there a few tried and true steps. One is to separate the two warring sides so that they can't escalate fear or damage.
This is a massive undertaking, but i don't see anyone trying to bring America back together. You ask good questions. Your worries about where we're headed are justified. And I'm going to add at least four answers to the FAQ based on this. Thanks!
