I was raised in a Conservative Christian home, and until my Junior year of High school, I was a Pro-Life, Conservative, Creationist, Republican. By the time my Freshman year of college was over, I'd become politically moderate in most regards, and am now very frustrated with the religious fanaticism I saw first hand through most of my youth.
To the credit of my parents, they were not among those who wanted the world to end or thought the Rapture would happen on the stroke of midnight at the beginning of 2000.
But they sent me to private schools where such views were expressed.
I still remember a teacher laughing at and ridiculing me because I questioned The Rapture and it's plausibility. It was one of the most frustrating moments of my life, and the moment I realized that there were people for whom logic and the facts would never get in the way of their preconceived notions.
The article I'm linking to below is an excellent summary of the Rapture focused ideas that I find so abhorrent.
There are plenty of Bible verses that make it clear that the idea of "The Rapture" is nonsense, but I won't go into it here.
Their beliefs are bonkers, but they are at the heart of power
