Do you know what deism is? I think you are confused and possibly suffering from liberal indoctrination you are unaware of. This deist junk concerning the Founders is propaganda...
To quote from your link: "I believe in one God, creator of the universe. That he governs it by his Providence."
Deists believe there is some higher being unknown that set everything in motion and then checked out -as in no eternal life, no reason to observe 'good' vs. 'evil', no providence, etcetera...
Suggest you deprogram and reevaluate with fresh data...
There are Deists who believe in a Creator but not an active God, but anyone who reads Thomas Jefferson's writing or Ben Franklin's writing did believe God checked out. And neither do I.
