I can guarantee a few things:
This time frame might conveniently exclude certain events that might make the Muslim figures more even in how many killed whom.
- More Muslims have been killed by Christians over the last decade than Christians that have been killed by Muslims.
2. More Christians have been killed by Christians through acts of war, acts of terrorism, personal acts of violence, etc., than have ever been killed by Muslims.
This would be possible, but would also bear comparing to how many Muslims killed their own. Right now in Iraq, Iran,A'stan, P'stan Muslims are killing Muslims as well.
3. Over the last 100 years, more Jews have been killed by Christians than have ever been killed by Muslims.
Well, I guess we may have no choice but to accept that Hitler and many of his followers may have called themselves Christians.
3. Almost none of the more than one billion Muslims in the world have ever committed any act of violence against a Christian.
Not sure by how many the # of Muslims outnumber the # of Christians in the world, but surely the majority of Christians have not committed any act of violence against a Muslim either; or other Christians. To the credit of many Christians, they do NOT hold the enitre Muslim population responsible for a few of the extremists. Some may, but I don't think there are as many as there are Muslims who believe non-believers should be summarily executed (not just Christians, but anyone not a Muslim).
