The ridiculous argument of atrocities done in the name of Christianity is false. Anyone can say they did an atrocity in the name of Christianity. The truth is they were going against the word of God and that’s the point,going against the word of God only leads to chaos and misery.
Those Christians will say that they understand the word of God, that you are a heretic and shall burn in Hell. Everyone seemingly has their own interpretation of Biblical scripture and the immoral fundies can’t be just brushed aside because they’re inconvenient. Your religion isn’t a gurantee of righteousness. It can form moral codes, not always good, sometimes so, but it can cause some justification for atrocities.
