The words 'God', 'Jesus', 'Creator' & 'Marriage'.
Now, if 'America was founded on Christian values' as per your claim, then you'd have thought that those very Christian Founding Fathers would - in the drawing up of the document that is the very basis of your country, the US Constitution - have thrown those words around like confetti, would they not...?
I hereby challenge you to find the words 'God', 'Jesus', 'Creator' & 'Marriage' in said US Constitution.
To make it easier for you, simply click 'Edit', then 'Find' on that page, then type in those words one after the other.
But I warn you now, shitwell(IQ)5.3: If you can't find just one instance of the words 'God', 'Jesus', 'Creator' & 'Marriage' therein, then you will, by definition, therefore admit that America is not a Christian Nation, and that fact will be the least of your problems, frankly. For if those other religions have protection under the same Constitution, yet you admit that yours isn't equally a religion, then not even yours has the right to exist, as not even the IRS recognise your 'be-liefs' for tax-exemption on such, therefore it's open season on you & your 'non-religious' ilk, and you don't have the right to complain when it's Fundie-Bashing time; you certainly don't have any legal recourse, as per that same Constitution.
...but to have those protections, you would be forced to admit that yours is a religion too. Thus even $cientology's L. Ron Hubbard - 'LRH'/'Commodore'/Source' - is equal to your 'God'. Enjoy your argument-annihilating paradox then, shitwell(IQ)5.3. >:D
