If the sky opens up on that day and all these things come to pass as predicted, I will repent. Will those who made this prediction repent when May 22nd comes along and nothing has changed? No! They will merely claim they miscalculated.
Full disclosure: I was called a “nasty individual” for pointing out the May 21, 2011 prediction and asserting that anyone who presumes to predict such a specific date is a nut job. I stand by my assertion. :) I’ll try to remember to ping you on May 22 — if we’re still here.
