Isn't that like a really inadequate answer to people trying to critisize/improve things? I sure get the rednecky "If you don't like this country mister, then go live somewhere else" vibe from it.
Clearly the fact that you are satisfied with Go doesn't stop you from inteferring with people having discussions about its (perceived) shortcomings.
So why should my disatisfaction with it prevent me from discussing it Especially if its a dissatisfaction with some aspects of it, and not the whole thing? By the same logic, nobody should use anything (nor complain about anything), since all languages have shortcomings that they don't like.
