I'm not sure he was anti-organized religion so much as he was against the Danish state Lutheran Church. And while he was individualistic he certainly believed that religious absolutes existed outside the individual, he just didn't think one could discover them via reason, thus the "blind leap of faith".
Probably some Kierkegaard quote about how religion is irrational. As if Reason is a god. These folks need to read their Kant.
As for Heraclius, will the public school teach that he absolutely destroyed the Sassinid Persian empire, and was one of the more successful Byzantine emperors?
