No, it's not a spelling mistake. Its just a joke about JP's obsession with sex.
I'm going to briefly recount JP's false arguments "proving" god and the divine origin of Torah, along with a 1-line rebuttal.
Claim: There is no morality without God or the Torah.
Rebuttal: People make laws to make livable societies, while individual guilt, conscience, and empathy are part of human nature (except for psychopaths), and give an evolutionary advantage in helping perpetuate our genes.
Claim: The watchmaker analogy proves that there was a Creator.
Rebuttal: The watch is not analogous to biological material, which we observe to grow, replicate and change itself without "intelligent" intervention.
Claim: The mass revelation claims made in the Torah could not have been fabricated.
Rebuttal: Yes they can, as can be all claims made by other religions.
Claim: The feeling of free will and self-awareness proves that we have an immortal soul.
Rebuttal: That we have those feelings says nothing about what causes those feelings.
Claim: Atheism produces immorality and degeneracy.
Rebuttal: As a proportion of the population, violence in the world is decreasing, as the world is becoming more secular. (Proof: average lifespan has increased despite wars)
Claim: The Torah contains unique wisdom that could only have been written by God
Rebuttal: The Torah contains plenty of mistakes (factual errors, contradictions and anachronisms) as well as customs and stories copied from neighboring peoples.
Claim: The Torah and Judaism don't change.
Rebuttal: The Talmud and subsequent rabbinic interpretation completely changed Judaism, nullifying some laws and adding new ones.
Claim: The oral law is from God and was given to Moses
Rebuttal: The Bible itself contradicts this in many places. The Talmud at times completely twists the words of the Torah.
Claim: Justice is administered through the afterlife and hell.
Rebuttal: Absolutely no evidence for this other than rabbinical statements in post biblical times.
Claim: Skeptics most prove their skepticism, i.e. that God doesn't exist or didn't write the Torah
Rebuttal: The flying spaghetti monster and celestial teapot arguments demonstrate that the burden of proof is on the believer, not the skeptic.
Claim: Evolution is an unproven theory promulagated by atheist crackpots.
Rebuttal: The overwheming scientific evidence (direct observation+inductive reasoning) shows that it is correct, and it is held to be true by the vast majority of biologists and has stood the test of scientific scrutiny. (Had it not withstood this scrutiny it would have been dropped long ago like blood-letting or exorcism).
Having said all of this it may still be rational for a person to believe in God and OJ, as long as he recognizes that it is a leap of faith for which there is no proof. I wouldn't call all of the religious people on earth "irrational", unless their faith brings them to do destructive actions to themselves or others.
