Hi Lakhota, respectively, from one atheist to another, let me disagree with a few comments you made. First you wrote, "How far has religion advanced? Zero". However, surely you don't believe that living with the Aztecs who killed 10,000 people a year is the same as living in Mexico today. Back in the 15th and 16th century, over 100,000 "witches" were killed in Germany by the Protestants and Catholics. Certainly you would notice hardly any witches are being killed in Europe these days. Of course religion (or most religion) has changed and advanced.
You also wrote, "Just think how far medicine has advanced since biblical days". This is certainly true but it should also be pointed out that many advances in science and medicine have been done by scientists and doctors with religious beliefs. From Isaac Newton to Galileo to Archimedes to Albert Einstein to many,many,many others. These are hardly people known for their stupidity.
Finally, I would just add that the worst atrocities committed by any religion pales in comparison to the atrocities committed by totalitarian regimes of the 20th century. Stalin, Mao, Pol Pot, Hitler all rejected God while relying on faith in themselves. Replacing God with the state never ends well.
Needless to say, the hallmark of the left seems to be an irrational FAITH in the government... and that is one religion I'll never understand.
