You mentioned sports. Tennis or golf players shake hands at the end of a match. You don't see Tiger Woods saying Rory McIlroy that he's an infidel who must pay the jizzya with willing submission. You don't see Fernando Alonso (a high priest in the Holy Church of McLaren) say it's McLaren or the highway, and that Kimi Räikkönen and Ferrari are infidels which will burn in F1 hell. Nothing is as gratuitously divisive as religion.
You've mentioned Jesus a few times. I'm curious, can you provide an example of a fundamental claim he made that was "already known... and...fairly well distributed"?
Since all gospels are at least half copied from Mark (who was he?), and since Mark contains obvious mistakes (geography) and tall tales (healings, resurrection), I would like to know what part of the gospels are quotes of a real Mr Jesus. And then which quotes you consider to be both reliable and bringing innovative moral insights.
To be fair, I like the story of Jesus and the woman taken in adultery
If only because it kind of nullifies the Old Testament and the Quran.
Alas, I hear it's probably not even an authentic part of the original John
(John whose book must have been written under the influence of serious weed smoking)
