Ayn Rand was sure as Hell no "lefty", and she was an atheist, Atheism is NOT a political issue, nor is agnosticism.
And of course, the real issue is not whether there is or ever has been a creator, but whether the specific creator, the loving god that God fearing Christians also think should be feared, is that creator deity.wiped out
The character called "God" is quite different in the Old Testament from the same deity also known as "God" in the New Testament.
We know for a fact that "God" as described by Jesus was going to appear very soon and wipe out the Roman Empire and the entire world and take over and rule the planet. Paul also described the same deity.
And we know that Jesus and Paul were both wrong. "God" did not wipe out in injustice at any time that could be described as "soon".
