Oh, so "religious fanatics" are people that have a deep faith in Christ? Glad that you admit it!
No, acludem, the founding fathers did not want to have a government that imposed a state church on its citizenry as England did. That is what they were talking about. Not driving religion out of public life. You are confusing Jefferson, Hamilton, Jay and Madison with Marx, Engels, Lenin, Mao and Stalin.
Other lies perpetuated by the Left ... Lincoln was gay and Jefferson had a million kids with his slaves. The First Amendment protects pornography (it doesn't, it protects political speech). The Founding Fathers had gay marriage in mind when they drafted the Constitution and of course, their vision of America was like something from the "Communist Manifesto".
And if you really want to keep with the true spirit of the Founding Fathers. The goverment was originally designed to be almost entirely out of its citizen's hair. The Founding Fathers were in favor of a central government that did not involve itself too much with the lives of its citizens, except for providing for defense and "the common welfare". So let's start dismantling this lumbering behemoth of government which is more in line with the vision of FDR and the New Deal Democrats rather than the Founding Fathers.
I believe that the "fanatics" are the people who are trying to extricate religion from public life, not the ones who occassionally (or habitually) pray. The ones who are obsessed with religion are not the ones who uphold the Ten Commandments but the ones who are trying to erase them from public life (like you, perhaps?). The ones who are constantly crying in front of a judge that the Boy Scouts are evil because they teach traditional American values. And the reason they go to judges rather than the American voter is that they would get voted down in a heartbeat if they had to rely on the typical American voter to advance their agenda. Of course, these fanatics don't believe in a pluralistic society, but one ruled by an elite class of judges and citizens who "know better", in short, an oligarchy.
Most of these " religious fanatics" that you talk about are not Elvis look-a-likes with bad hair and a southern accent, but people who go to church, (some only on occassion). They want their kids to grow up with a solid sense of right and wrong, not because they want them to hate homosexuals and atheists, but because they want to protect them from the consequences of evil and immorality (like VD, AIDS, abortion, drug abuse, constant depression and so forth).
