The problem with your argument is that America does, in fact, have a Christian heritage as documented
here, by me.
No reasonable person would dare suggest that Islam or Satanism should play any role of influence in our society. There is simply no historical precedence for it.
Christianity, by contradistinction, does play a major role in our history.
Yeah, a role that the founding fathers of this country were eager to get rid of.
"The government of the United States of America is not in any sense founded on the Christian Religion"
-John Adams
"During almost fifteen centuries has the legal establishment of Christianity been on trial. What have been its fruits? More or less in all places, pride and indolence in the Clergy, ignorance and servility in the laity, in both, superstition, bigotry and persecution...In some instances they have been seen to erect a spiritual tyranny on the ruins of the Civil authority; in many instances they have been seen upholding the thrones of political tyranny: in no instance have they been seen the guardians of the liberties of the people. Rulers who wished to subvert the public liberty, may have found an established Clergy convenient auxiliaries. A just Government instituted to secure & perpetuate it needs them not.”
-James Madison
"Mingling religion with politics may be disavowed and reprobated by every inhabitant of America...All national institutions of churches, whether Jewish, Christian, or Turkish (Muslim), appear to me no other than human inventions set up to terrify and enslave mankind, and monopolize power and profit."
-Thomas Payne
“Of all the systems of religion that ever were invented, there is no more derogatory..., more unedifying to man, more repugnant to reason, and more contradictory to itself than this thing called Christianity. Too absurd for belief, too impossible to convince, and too inconsistent for practice, it renders the heart torpid or produces only atheists or fanatics. As an engine of power, it serves the purpose of despotism, and as a means of wealth, the avarice of priests, but so far as respects the good of man in general it leads to nothing here or hereafter.”
― Thomas Paine, The Age of Reason
“But how has it happened that millions of fables, tales, legends have been blended with both Jewish and Christian revelation that have made them the most bloody religion that ever existed?” – John Adams, letter to FA Van der Kamp, December 27, 1816.
"Christianity neither is, nor ever was a part of the common law."
-Thomas Jefferson, letter to Dr. Thomas Cooper, February 10, 1814
"History, I believe, furnishes no example of a priest-ridden people maintaining a free civil government. This marks the lowest grade of ignorance of which their civil as well as religious leaders will always avail themselves for their own purposes."
-Thomas Jefferson to Alexander von Humboldt, Dec. 6, 1813.
"They [the Christian clergy] believe that any portion of power confided to me, will be exerted in opposition to their schemes. And they believe rightly; for I have sworn upon the altar of god, eternal hostility against every form of tyranny over the mind of man. But this is all they have to fear from me: and enough, too, in their opinion."
-Thomas Jefferson to Dr. Benjamin Rush, Sept. 23, 1800
