I have news for you - for the last 200 years religious Americans have been running this country (in government and courts), and, as you know, no one has been persecuted because of their believes or non-believes...so you can't complain about religion in America...I hope you are smart enough to see the difference...
something doesn't come from nothing - our Founding Fathers, although had acknowledged that religious persecution is very wrong and not to be tolerated, had religous believes/values, and their believes had been guiding them in founding this country (like that people are created by the Creator and are born free, etc.)...they were not atheists or agnostics, they were Christians of different denominations...now you can't point out of a society that even remotely resembles the US in religious or non-religious tolerence and had been founded by people with no religious convictions, can you?
