Unbelievably petty, to my mind. People are hypocrites and need to remove the plank from their own eyes, so to speak. I certainly wouldn't want every foolish or thoughtless thing I said at 15 plastered all over the internet for posterity (and thank God the internet didn't exist back then). It staggers me that people cannot contextualise such behaviour. It demonstrates an astonishing lack of compassion, understanding, and a cruelty in punitive measures greatly in excess of the (already apologised for) offence.
