When you're in the limelight, and a entertainer, actor, politican, or some other well publicized individual, this type of thing is bound to happen sooner or later if you're not careful. Especially with so much portable recording technology surrounding us. You make a totally innocent remark, not meaning to offend anyone, and the media will run wild with it. Sarah Palin has been fighting this since day one, and it seems after the Tuscon / Giffords shooting she has learned to stop being so defensive.
I agree he had nothing to apologise for. But he was also wrong to utilize Hitler in making ANY analogy, regardless of how he meant it. Because it in itself is going to be taken wrong by many, and will come back to haunt you as this has with him. It's one thing for us guys to say this kind of $h!t around here, or at a bar. But it's quite another for a popular, public figure to do it with microphones and cameras turned on. There just was no other way for this to turn out except bad. Much like the Fuzzy Zoeller, "fried chicken" comment he made about Tiger Woods, this is going to wind up costing him a fortune, much like the "Jimmy The Greek" restaurant comment about blacks he made, cost him his job with CBS on "The NFL Today". He wound up losing millions over just one slip of the tongue after a few drinks. If you're white, and you make ANY comment about blacks in a negative light, it's going to turn out bad. Political correctness at it's finest.
