He said that alot of christians try to be "politically correct" and wiggle out of this question for fear of "turning" people away.
I think your uncle is quite mistaken in this statement. First, most christians do not profess belief in such a doctrine. Therefore, they are not "wiggling out" of consideration of it, in order to be "politically correct". Secondly, most christians would be repulsed by such a teaching. Your not the only one who wouldn't want to worship a god that would do such a thing. The sad part is, there are some people who would and do.
