Why all the anger towards Colbert? I don’t see any backstabbing going on here.
I'll give you the shortest answer possible.
Although I can't think of anything Colbert has said that was insulting to the US Servicemen and women, I can think of plenty of things he's said that was less-than-flattering of their mission.
Also, Hope comes from a time when comedians used to be much more self-deprecating and good-spirited than what they are today. No one could accuse Bob Hope of making a snarky comment. But, with Colbert, Stewart et. al., that's all they ever do. They're just very well paid, incredibly unbalanced smart asses. That's the difference between them and Bob Hope.
