&gt; How to know if a religion is the source of an action or not? One way is to look at the founder of the religion.<p>This is absurd and ignorant reasoning. I don&#x27;t think I&#x27;ve ever, in my life, wondered what the &#x27;founder&#x27; of my religion would do. I highly doubt most people do, and I&#x27;d like to see some evidence - some research - showing that it influences more than a tiny fraction.<p>Every religious scripture has extreme (by today&#x27;s standards) violence in it, including the New Testament. And Christianity, Islam, and Judaism all have the same founder: Abraham, and the founding act was his extremist obedience to God, when he attempted to perform the human sacrifice of his own son.<p>I encourage you to read those three scriptures (the Old Testament is long, so at least the first 5 books there, which make up the Torah); it dispells a lot of ignorant rumors that go around.<p>(Based on what I&#x27;ve read about, and the little I&#x27;ve read of the Quran, the Old and New Testaments are regularly cited, and Moses and Jesus are considered prophets.)
