The last Crusade and the Inquisition ended more than 700 years ago. There were small pockets of injustices done in the name of the Church in Spain's conquest of the American southwest more than 400 years ago and in Colonial America some 260 years ago. Since that time there have been no conquests, massacres, or broad based punative measures of any kind advocated by the Christian Church anywhere. Those who have gone to war have not done so in the name of the Church.
Just this past week Egyptians were burning Christian Churches because of rumors that az new church building would be built. Radical Muslims are pledged to destroy all infidels in the name of Allah. In the 20th Century totalitarian leaders banned all religion, most especially Judaism and Christianity, and massacred millions.
The vast majority of the world's orphanages, free hospitals, soup kitchens, homeless shelters, schools provided for the world's poorest people, leper colonies, and other ministries of mercy and relief are funded and staffed by Christians.
Those who want to paint Christians as the blood thirsty evil people of the world are not only prejudicial and ignorant, they are bigots.
And this atheist pretty much single handedly keeps the food bank going at the local church.
