Let's sum up: I believe it would be totally just if our society stoned gay people to death. That doesn't make me a homophobe since I'm not suggesting we actually do it, not just right now. It does make me a Christian, since Christianity is defined by an obedience to Biblical law.
Wow, how much ignorance can you pack into one politician?
Thinking gay people deserve the death penalty isn't just homophobia, it's barking-mad homophobia.
Asserting that being a Christian is about obeying (some, but obviously not all) Biblical "laws" is to redefine Christianity to something unrecognizable to even most conservative theologians.
