The specific line that was cherry picked wasn't guidance, it was a warning to the Babylonians who held the Jews captive and committed atrocities against them that the Babylonians would have the same done to them.

Wait wait wait... you're saying this guy, who believes religious folks cherry-pick quotes from the bible out of context in order to support their preconceived beliefs, went ahead and cherry-picked quotes from the bible in order to support his preconceived beliefs about those very people?

That has gotta be the most meta thing I've ever heard...

Or maybe that's just hypocrisy. Potato potahto, I suppose.
