One demonstrably false scary Iran story gets shot down rather quickly, though it of course will remain in circulation in wingnuttia and elsewhere forever. More stories will come which won't be as easy to shoot down. And the problem is, of course, that Iran doesn't have an especially pleasant government so people like me find ourselves in the unfortunate position of appearing to defend people who aren't necessarily great examples of humanity when all we're doing is trying to figure out what the truth is.
And around we go.
