We should be ready to have these technical discussions and encourage them, not be so strangely defensive about it as you seem to be.
And I do love technical discussions around Go vs any of those or other languages, or indeed even discussions having nothing to do with Go, but I'm tired of all of the hateful comments Go developers get.
If I seem defensive it's because I am constantly put on the defensive.
The only one framing the debate so negatively here is you. As a fan of "Go" you should be taking the opportunity to educate people about it.
Instead, I'm left with a bad taste in my mouth. Let's hope this mood is not representative of the Go community.

These are the comments driving my responses which are negatively addressing the developer's choice of language, and those are only the ones on this thread. I'm sick of Hacker News trying to make developers feel guilty for using a technology.
I have not argued against anyone asking "why" in regards to what language they feel is best suited to the task at hand. Obviously that question needs asked for any project. I am arguing against everyone whose instant response to "we built X in Go" with "oh god why would you do that" types of "why". There is a distinction in those whys, and if you cannot or will not recognize that distinction then that is your own failing.
I am not involved with or representative of the Go community. I represent only myself.
If you use something else and decided to switch to one of those languages, someone might well ask why. Rewriting is almost always a decision that needs some justification.
People ask "why?" about conversions to those languages all the time (if you converted a web project from PHP to C/C++, I'd expect you'd get more "why?" questions than doing the same thing from PHP to Go.)
