Christians are ok with that, because they think they'll have been raptured already.

It's all bullshit in the end, but I personally know many people that hold that view that consider themselves Christian. In fact, they think Catholics aren't Christian and are going to hell, because they worship idols.
More specifically, when talking about US politicians like Mike Huckabee that spout off weird religious stuff like this, you can assume protestantism at least, if not fundamentalism and associated woo.
Your disdain for Christians is noted, but my point is that your original comment is an oft-repeated, incorrect interpretation of what most Christians have believed since the very beginning of Christianity.
