Unless they killed in the name of atheism, the fact that they were (or weren't) atheists isn't an issue.<quoted text>
20th century soaked in the blood of atheist governments.
East Germany, the Berlin wall,
who wished to leave.
Twentieth century atheists in power resulted in mass murder.
No wonder neither political party nominated atheists for president.!
Neither party nominated an (open) atheist because an atheist can't win in the US.
