What if your problem is not Fundamentalist Christianity? What if your main problem is the restrictive notion that: it is not OK to be not OK with someone/some group?
I felt much more free when I let go of the notion that I had to be OK with everyone. Some people are so superstitious and/or ignorant and/or hateful and/or hostile that I do not feel obliged to see them as my human brethren that I need to love- regardless. Sure, if I saw one drowning or about to step in front of a bus, I'd pull her out. However, I am comfortable with the idea that at least part of my motivation for such actions would be based in a holier-than-thou framework.
