Unlike Atheists, who though few in number, murdered 100 million people in the last 80 years. But, then, they aren't as highly evolved.
Unless you're claiming there's an organized church of atheism, this isn't much different from claiming that right-handed people murdered 100 million people.
What I don't understand is how a Christian could use force and murder in the name of God simply to convert others to their "religion of compassion".
Mmmm, lets look at a few examples of compassionate Christians. Some of these are close to home, so listen up...
The holocaust was largely perpetrated by practicing Christians from a Christian country.
The keeping of people as property in this country was largely perpetrated by Christians.
The seizure of our country from the people who already lived here, along with their unfortunate near-genocide was largely perpetrated by Christians.
The stamping out of the Philipine's insurrection was perpetrated by Christians.
Christians institute strategic bombing campaigns against the civilians of enemy regimes.
Down through history Christians have repeatedly used extreme violence against pretty much every other culture they encounter. (as well as endlessly against each other)
We were Christian nations all that time and that hasn't changed, so you'll have to forgive me for doubting that the compassionate nature of Christianity is what makes us behave a little better over the last few decades.
I am not saying that we should be blamed for the actions of our ancestors (though as I understand it Christianity says we are to blame for the actions of our ancestors so you may disagree) but there is rich comedy in Christianity pointing the finger at others in the violence stakes.
