Hi Ron, you might read this:

It seems that Chomsky agrees with your view that offensive language is sometimes necessary. Citation: "...And I agree that I am litigating all points (all real, as far as we have so far determined) in a “plodding and accusatory way.” That is, of course, a necessity in responding to quite serious published accusations that are all demonstrably false, and as I have reviewed, false in a most interesting way..." And now I realize what you mean. Because Sam stopped discussing the topic because he (as you can read) wrote that Chomsky was too offensive (rephrased in my words). So it helped to expose the truth a bit I think. If Chomsky wasn't right, then it should be easy for Sam to refute some of Chomsky's arguments, but he just stopped the discussion and cried about Chomsky's language. (sry for the edits)
