what is enough? NOTHING. What does sorry mean, really? He's sorry he said it out loud...that doesn't mean he doesn't believe it. So why on Earth should the ADL accept an apology and furthermore...I don't even believe Gibson should apologize...he hates Jews, so why does he care what the ADL thinks. Believe me, he doesn't. This is to salvage is image.
The apology wasn't TO the ADL, and it's not real likely that Gibson cares one way or the other what Foxman thinks.
Foxman, imo, is nothing but a Jewish Jesse Jackson. Both Foxman and Jackson are, first and foremost, leftists; secondarily, they are shake-down artists and publicity hounds.
So, even when they DO get it right itregisters as no more than a broken clock giving the right time 2X a day.
