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.
Absolutely. He is a smart man, but his purpose ultimately is to sell a lie, and he even so much as admits it. When I read his work I was a true believer. OFC this was in the context of George Bush Jr., which I still stand by him being net negative and a tool of his father (as other POTUSs were). Luckily I had a strong background in psychology and philosophy so I started to see the contradictions and cognitive tricks played to sell these ideas. Along with a little more life experience, and a rapidly shifting Overton Window, suddenly my once liberal ideologies are now "far right" to some people.
As you state though, that is one of the primary weaknesses of the left. They like to pretend to know about you and your ideas, but they hardly know their own. If you don't cultivate your mind, other people will, and it will not be for your own good. Collectivists love it though... for a while...
Tucker Carlson vs Chomsky in a debate, Chomsky would lose.
