I don't think this is accurate. Atheistic communism is a relatively modern development. I agree millions were killed because of it but if you compared fatalities as a percentage of current population there would certainly be more killed by religious groups than non-religious. "Christianity" has an almost endless list of atrocities throughout history. Here's one example from the CrusadesJosh wrote:The most violence ever seen in human history can be laid at the feet of Communism, which is explicitly non-religious. By that standard, religious people of all kinds of religions are less violent than atheist Communists, who brought us the Soviet Union, communist China, and Pol Pot, with hundreds of millions killed.
The argument religion is what leads to violence is just anti-Christian sentiment from people who want excuses for why they don’t believe in God.
According to the Gesta Francorum, speaking only of the Temple Mount area, "...[our men] were killing and slaying even to the Temple of Solomon, where the slaughter was so great that our men waded in blood up to their ankles..." According to Raymond of Aguilers, also writing solely of the Temple Mount area, " in the Temple and porch of Solomon men rode in blood up to their knees and bridle reins." Writing about the Temple Mount area alone, Fulcher of Chartres, who was not an eyewitness to the Jerusalem siege because he had stayed with Baldwin in Edessa at the time, says: "In this temple 10,000 were killed. Indeed, if you had been there you would have seen our feet coloured to our ankles with the blood of the slain. But what more shall I relate? None of them were left alive; neither women nor children were spared."[24]
Christianity is to be the only religion where people "loved their enemies". This is impossible without God's love flowing through us by the infilling of the Holy Spirit. We need to say, and show by example, that Christianity forbids violence!
All through history pseudo christianity has sought to govern and thereby christianity is known by the onlooking world as another violent religion.
