Hmm ... if religion is organized, who is at the head of it? If it is popular why are all these people cheating on their spouses and killing each other? Perhaps you are referring to the worship of sex and consummate professionalism as a "religion"?
As far as you're concerned, though, if people taught flat earth theory in every school, would you -from your death bed- look back on your life and say it was all a waste? How would that affect you?
