Err...the founding fathers criticized religion, like, all the time. Jefferson, Madison, Paine, Franklin, Adams...all had pretty radically dissenting views from the norms of the time, and weren't shy about it.
They skipped that part when I attended Oklahoma public schools, too.
Did they skip lessons in reading comprehension as well? If you'll re-read the sentence of mine that you take issue with you'll notice that I did not make any statement as to the particular religious beliefs of the founding fathers. My point is simply that they believed that everyone has the right to freely practice religion as they see fit without ridicule. This can be seen in Jefferson's famous separation of church and state letter by simply reading the first sentence of the following quote:
Believing with you that religion is a matter which lies solely between man and his God, that he owes account to none other for his faith or his worship, that the legislative powers of government reach actions only, and not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should "make no law respecting an establishment of religion, or prohibiting the free exercise thereof," thus building a wall of separation between church and State.
Madison is widely recognized as the framer of the first amendment. I think the fact that he believed in freedom of religion is fairly obvious.
Paine was definitely a self professed deist, but after reading some of his works, I haven't read anything to make me believe that he would deny the right of any individual to have their own beliefs.
In a letter to the President of Yale, Franklin wrote:
"I have ever let others enjoy their religious sentiments, without reflecting on them for those that appeared to me unsupportable and even absurd. All sects here, and we have a great variety, have experienced my good will in assisting them with subscriptions for building their new places of worship; and, as I never opposed any of their doctrines, I hope to go out of the world in peace with them all.
In summary, it should be abundantly clear that the founding fathers respected the right of every man to practice his own religion. Ridiculing others for practicing this right does indeed fly in the face of what they believed.
