"The core of all of them is to treat others as you would yourself (or better)." This is the biggest problem of many religions, this is a WRONG concept. A wrong premise has a consequence bad results. Why it is wrong?, very easy, if you hate yourself applying this concept you will hate and harm the others! Tell me how many people hate themselves, is so common..... The secret is, before anything you must love yourself first!

Stupidity also evolves!
