OK folks, let's get a tiny bit back on track here.
The author who got booted quite literally says: "The Bible has incest in it. So Amazon, if that's why you dropped my book, then you should stop selling the Bible as well."
This claim is, as I said before: absurd, childish, trivial, fatuous, specious and so forth. This specific argument has absolutely no merit.
You are all welcome to be heathens if you want, that's none of my business.
But the various opinions of the Old Testament itself are simply not relevant to this particular claim, and do not bolster it in the slightest.
