I don't know how it came to be that compromise is intolerable to so many, or at least, seems to be.

When I was growing up and going to Sunday school (Methodist), intelligent design was what most reasonable religious people seemed to believe. Of course, they didn't take the bible literally, and this was necessary to compromise between the Bible and science. I don't even remember hearing about creationism, although I don't doubt the belief existed.

Not being able to see the good in people because they don't believe the same things as us is one of our biggest shortfallings, IMO.
