'I'm in part Bosnian, so American intervention has had a very real impact on my family's well being and even survival. So I'm at least ambivalent if not opposed to some of Chomsky's views on anti-imperialism, even though I respect his principled stance.' That does not matter. It doesnt make your opinion more valid. 'Calling this or other things "genocide denial" and similarly extreme terms is a common tactic in order to craft an ad-hominem attack to divert from anti-imperialist criticism.' It is very normal to judge based on other areas that someone said. He denied the Cambodian genocide and never changed his view since 50 years! What does it say about him? And why is it ad-hominem? Do you even know what does it mean?
