First, I'd suggest reading some newspapers. Second, I'd suggest some history books.
Please heed your own advice.
That "fairy tale", as you so inelegantly put it, was at the core of most of the Founding Father's philosophy. Read the Declaration of Independence (Jefferson) and/or the Federalist Papers (Madison, Hamilton, Jay)--the most compelling combination of philosophy regarding the rights and responsibilities of man ever put to paper. And thoroughly steeped in both secular philosophy (Hobbes, Locke, etc.) and Christian philosophical morality.
Wait-wait...I can hear you already: "But Thomas Jefferson owned slaves! Hmmph, some morality!'". That is true. He also did not advocate women getting involved in political affairs.
But on a higher plane, perhaps his redemption is in the everlasting words he wrote that "all men are created equal"--a phrase that despite it not being in an official government document (it ain't in the Constitution, it's in the Declaration of Independence which was essentially a letter to the King of England) has come to codify the core beliefs of all Americans. It rallied abolitionists prior to the Civil War and motivated the President (Lincoln) during the Civil War. Those words served to fight the injustice of Jim Crow laws through the 40's, 50's, and '60s, and still resonate today. Although Jefferson did not live by this ideal during his lifetime, his words profoundly shape us now...and the rights he spoke of he claimed were "endowed by [our] Creator".
Jefferson was not a "lockstep" Church member in the slightest--he suggested to question the existence of God many times. He was highly interested in biblical philosophy, theology, and morality...and those pursuits show in his writing and legacy. Are you willing to give up the ideal because the origins of the ideal were not conceived "perfectly" and were conceived by referring to Christian ideals?
His "clear-thinking" did not denigrate the beliefs of others as you have, nor did he "hate" religion as you profess to do. He gleaned the best of the religious world--the philosophies and morality--and incorporated those with the best secular philosophers of his day to produce work of stunning righteousness and clarity that affects all individuals who read it to this day. Hamilton, Jay, and Madison did similar work in the Federalist Papers that shaped our Constitution.
"Hating" religion is just not smart, nor will it give you insight for the future (you know, since 90+% of people in this country consider themselves religious).
