Despicable? To quote a semi-recent movie, "Your moral compass is so skewed I'm not sure you can find your way to the parking lot." Not outing, but merely threatening to, a swill spewing bigot is despicable?
Despicable, where I come from, is bigots spreading their poison from behind a mask of anonymity. What CNN done wrong, here, was to NOT complete the play. They should have published his name and location.
The issue here is not "meme creator needs to be outed". It is "President's source of childish video turns out to be anti-semite scumbag coward who has not the courage of his convictions."
His apology rates with those that you hear at sentencing hearings. "Sniff! I'm so sorry. Sob!" What they mean is "Gee, I wish I hadn't been caught at this. Now I don't want to put on my big boy pants and pay the piper, so gosh, you could like let me off with a warning, right?"
