The "Existence of God" debate

That’s a silly comparison. Science is based on evidence and reason, not faith and irrationality like religion; science and religion are opposites. Nor does science have any “sacrosanct theories”; on the contrary, there’s nothing any ambitious scientist would like more than to tear down some well known or important theory - it would make his or her name in scientific history.

Which is normal for religions; Christianity stole a great deal from other religions as well.

All the other things that propel warriors, I expect.

No; they are strongly influenced by outside forces. And religion is a powerful force for corruption, both moral and intellectual.

It’s an acknowledgement of history. Christianity got to its present position through bloodshed, terror and destruction. All of its benevolent claims have throughout history overwhelmingly been empty rhetoric.
