Of course not. It is just demonstrative of the fact that most leftists don't even scratch the surface of understanding, even of the ideologies they support (or especially those perhaps).
Chomsky is an expert in linguistics, but he likes to pretend this extends to every field. He has openly admitted to being a tool of the elite anyways... and I agree, he is a tool. This however does not invalidate everything he has ever said. Even if every word he ever wrote was verifiably wrong, it still offers insight into specific ideological constructs.
Personally I'm indebted to Chomsky, for giving me more understanding of liberal progressive philosophy than 999 of 1000 liberals have.
This kind of understanding is only possible by reading the key documents, and understanding them.
Listening to and/or believing or parroting the current popular politicians simply does not do it.
