I'm aware of Chomsky's political proclivities, but this is purely a debate over the definition of "email". The nature of the actual systems invented is not in dispute, merely what to call them.
You said he was a linguist. I said that he hasn't done a lot in linguistics for many years now, which is true. I wasn't picking on Chomsky for being political.
Even much of his work in linguistics was polemics - the famous review of Verbal Behavior is pure polemics.
edit: and in interviews Chomsky has said that he felt a lot of this work had an essentially political purpose - talking about some nexus between Continental-style rationalism and opposition to totalitarianism, with which he associated the behaviorists
