My point was that it's easy to attack another Christian for their vote as long as you refuse to acknowledge just how awful your choice was. As it is we haven't had anyone to vote for for president with actual moral credentials in my lifetime except maybe Carter. The implication implied in the OP was that Obama is so evil that no Christian should vote for him in good conscience. I was just pointing out the obvious evil of the alternative who believes that he will some day be equal with God. Pot/kettle by that measure. Then you come back to who will cause less damage considering all measures.
Considering only abortion, which seems to be the practice of some, as much as I've fought for the lives of the unborn in the past 40 years, I realized long ago that when someone believes that abortion can be a choice it doesn't make them evil. Typically most believe it out of compassion for young women, not because they hate children. They may be misguided, in need of revelation of wisdom, but not inherently evil. Attacks and name-calling will never change their minds, only compassionate reason will. Abortion is evil; those who wrongly believe in abortion are not necessarily. As I've said elsewhere, abortion won't get you to hell one second faster than slander. Thank God we can repent from both.
