Any ideology can be taken to the extreme. The question is if the doctrine supports it. I'm not aware of any mainstream Christian sect that teaches murder or enslavement of non-believers, as essentially it violates one of the basic Christian beliefs, "Thou Shall Not Murder". Taking aberrations and asserting that they are mainstream beliefs is hardly credible. Perhaps I've missed something, so if you can correct me, please feel free. This contrasts sharply with Islamic, and for that matter religious Marxism/Statism, both of which advocate murder or wholesale enslavement of populations. Religious Marxism is responsible for the murder of literally hundreds of millions of people during the 20th Century, and Islamic Fundamentalism is an equally vitriolic force, yet has a ways to go to catch up to the Marxists.
