It is sort of like Global Warming. If someone wants to believe that stuff and just favors research into cleaner burning power plants, nuke plants, or better solar cells, I can compromise with them some and we can all live happily. When they want to establish carbon credits and otherwise destroy my way of life based on that kooky belief, that is when it goes beyond simply disagreement.

Hillary Clinton democrats are taking it way beyond live and let live.
