Q about arguments for God's existence.

[FatAndFaithless]

The christians who committed atrocities were not doing so because they were christians. They were not following christianity.

That's of course totally wrong. States that declared "atheism" as the "official religion" (that's exactly what it became, the State a Communist church) were not promoting any ideology that is inextricably linked or logically follows from the term "atheist."

You can't say that about the Church-States of Christianity that ruled the Middle Ages. There is no sense in talking about what "logically follows" from Scripture as it's all open to vastly contradicting interpretations, the only way to solve that conundrum by having an official Church, which directly led to the violence. Their actions against heretics were largely viewed as consistent with their Christian faith, especially given that outside of the "rulers" "God appoints" to ensure justice (and what's more just than slaying the infidel before he corrupts more souls?) there is no one to offer an "official" interpretation of Scripture. Killing, hatred against non-believers, suppression of dissent, and the like is inextricably linked to the "Good Book."

Not to mention all the countries recently in Africa and eastern Europe and elsewhere (Ireland for example) that have had humanitarian catastrophes based on the doctrines of their faith. The leaders and participants in these events all claim to be Christian. I'm glad Lek can tell who the real Christians are.
