America was founded on Christian principles, like it or not, and many still honor those principles to this day. One of those principles was a day of rest in observance of the Sabbath. Many believe that working on Sunday is a sin. Should America discard it's religious beliefs to honor your shopping/spending habits?
Hogwash. Most of the founding fathers were deists.
America doesn't have an official religious belief, nor does it have an unofficial one. It gives us all freedom to choose. If you choose to rest on sunday, since it is holy to you, by all means do it. But, don't pretend like everyone is with you on that and that we should roll up the sidewalks because you say so... it's simply unamerican.
America was founded on the ideal of freedom of religion for all. Christians took over and exerted political power to influence lawmaking once the founding fathers were gone. In fact, if your peaceful Christianity hadn't ridden on the pointy end of a roman sword in Europe, it would have died the same death as gnosticism, worship of Baal, and reverence of ancestors.
America's religious beliefs have changed as have it's need for more substantial proofs for religion due to a better educated population. The rotting carcasses of blue laws that still remain bear witness to the fact that Christianity had it's arm way too deep in the cookie jar of politics.
Around here, in Western North Carolina, business owners are afraid to open their businesses on Sunday for fear that the religious right will boycott them. This includes gun stores. And, that is really sad. Most of the people who would boycott are the same people with American flags in their yards or on their vehicles.
To miss the point of freedom of religion is to miss a major point of WHY there was a revolution in the colonies in the first place. And, subsequently, it means that you miss the point of the 2nd amendment.
I'm a neo-pagan. I'm American. I vote. I own weapons. And, I will stand and fight for your right to keep your sabbath holy as you see fit. Try doing the same for others when it comes to their beliefs and we'll all be in good shape.
