I think some of that stems from the fact that the arguments against Go are often over emphasised matters of personal preference, or just so frequently raised that it becomes tiresome to read.

I love Go. I know it's an imperfect language and because of that I do often hate specific Go idioms. So I definitely don't have a "bunker mentality" when it comes to Go; nor any other language. But in terms of "getting stuff done" Go has generally served me - personally - better than any other language. I just get a little sick of hearing about how Go is a "bad language" when what people actually mean is "it's not productive for them personally."

I can program in over a dozen languages, so I do have extensive experience outside of Go. And as someone who is language agnostic it never ceases to amuse and irritate me just how zealous people get when trying to prove personal preference as scientific fact.
