I'm firmly rooted in the American tradition which begins: We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
The 1st Amendment speaks of the liberty to believe as you wish, that you may practice according to your religious beliefs free from persecution so long as my beliefs do not largely infringe upon the rights of others. The 2nd Amendment can be understood as the right to protect oneself from the encroachment by others upon one's rights.

b) Founding Fathers wrote Constitution.
Therefore
c) Failure to believe in Great Big Fuzzy Kitty Way Up In The Sky = Beatles Fandom
There is a God after all.
