By that point you'll have posters so wedded to believing the false rumor that they'll be posting black helicopter, government conspiracy theories for why the "Iranian Missile Attack" never made it to a news web site.
I hope the story is false. However, you'll look far more foolish if this report is accurate than any of the people who believed in the report that they actually saw. It is smart to be skeptical but you don't need to be an ass about it.
