Bingo.
Noam Chomsky, Ann Coulter, Glenn Beck, and Rush Limbaugh are all of the same mold. Chomsky isn't even more erudite than the rest, considering how frequently he misquotes; he tries the Great Professor schtick but cannot maintain it very well.
The only real difference between them consists of their conclusions, but the fact that their fans hang onto the conclusions and ignore the intellectual dishonesty. Chomsky is more likely to embrace reprehensible regimes and people, which will be considered courageous (for people who like him) or scummy (for people who don't).
In all cases, it is possible for them to be right, by some definition of the word "right." Rush Limbaugh endorsed Snapple. Personally, I avoid buying Snapple because I don't like to give money to Rush Limbaugh, but there are many people who enjoy Snapple, and it's at least a fairly solid product. If Rush Limbaugh said that he enjoyed mashed potatoes, I'd still eat them, but I might not buy his brand.
