It really is the central view of, certainly, American and British media stars, that when, especially people with medals on their chests, who are called generals, but also high-ranking officials in the government, make claims, that those claims are presumptively treated as true without evidence, and that it's almost immoral to call them into question, or to question their veracity.
What's particularly strange about this set of personality and style attacks is what little relationship they bear to reality. Far from being some sort of brutal, domineering, and angry "alpha-male" savage, Chomsky - no matter your views of him - is one of the most soft-spoken and unfailingly civil and polite political advocates on the planet. It's true that his critiques of those who wield power and influence can be withering - that's the central function of an effective critic or just a human being with a conscience - but one would be hard-pressed to find someone as prominent as he who is as steadfastly polite and considerate and eager to listen when it comes to interacting with those who are powerless and voiceless. His humanism is legion. And far from being devoid of hope, it's almost impossible to find an establishment critic more passionate and animated when talking about the ability of people to join together to create real social and political change.
