Why the "There are so many interpretations of the Bible" claim is confused

[Mister Agenda]

So why do atheists frequently bring up the number of denominations? It's disingenuous to assert that it's a problem, then when it's defended, pretend like no one thought it was a problem.

To point out to you fools how you can't even agree among yourselves.  It's amusing to us.  One god but 40,000 religions.

Nothing dumber than a xtian.

Christians aren't particularly dumb. They just use their intelligence to justify continuing to believe what they already believe. Almost everyone does that, to some degree. As a social species, we largely use our brains to maintain our relationships, and continuing to believe what those closest to us believe is helpful for that.
