The fact that there are many principles contained in the gospels that would make the world a better place if applied correctly doesn't negate the fact that the same writings create a superiority complex among its adherents. This has lead to atrocities that can be placed directly on the shoulders of 'faith'. Other religions share in this so I'm not saying that Christianity is completely at fault. Religion and faith have caused more distress than anything else combined and that's what saddens me.
The Gospels, the faith, religion, all of these things are innanimate aobjects, they do not live, they do not move they do nothing.
People hurt people, let's put the blame where it belongs.
The core teachings of the Gospels are: Love God, Love yourself, Love your neighbor, love your enemies and forgive.
Yes, people have done horrific things in the name of God, in the name of religion, just as people have done horrific things in the name of progress, expansion, love, tribal unity, honour, pretty much anything you can think of, including doing horrific things because they have no moral Law and don't believe in one.
The blame is on people, period.
