I created this image for use elsewhere, but I thought it might be a good idea to have handy here.
Just to be clear: that's Ayn Rand's fans speaking in the caption, not me. I think Ms. Rand is a terrifying psychopath. The image is in the spirit of Infamous Brad's comment in Christians in the Hands of an Angry God:
There's always a catch. In this case, the catch must have been this. The traditional Republican party is the party of Satan himself, and thereby unpalatable to nearly all of the 90% or more of the US public that self-identified as Christian. I am not exaggerating here, not one tiny little bit. (Nor am I alone in this. Remember, I've met and done volunteer work alongside Dr. Michael Aquino, the founder of the largest Satanic church in the world, and you have never met a more staunch Republican in your life. Nor did he make any bones about why: he is a Republican Party loyalist because the Republican Party stands in total opposition to the Christian scriptures.) Throughout the gospels, take everything that Jesus said. Now reverse each and every statement. Each and every one of those reversals is a traditional plank of the Republican party platform.
Update: I just found this striking little video about Ms Rand by Johann Hari, linking her philosophy to her extraordinary biography.
