This is the sort of denunciatory rhetoric we don't allow on HN because it leads to flamewars, and of course because the vast majority of the time it's just cheap and ugly, with people attacking others for garden-variety reasons (fear, anger, projection), as humans do.
However, comments where people are criticizing their own background (country, in this case) are more complex and are a special case.
I wish I could dig up some of the moderation replies I've posted to commenters in this position over the years, but unfortunately my HN Search fu has failed to find any. (Edit: I did find a small one: https://news.ycombinator.com/item?id=15732812)
They also have a particular taste. As soon as I read this, I could feel that you were probably writing from that perspective. Such comments have a bittersweet quality. Even though the rhetoric is harsh, one can sense that the speaker has 'paid' for it with lived experience. Of course, coming from a minority inside that country, it gets even more complex. But I bet that if someone were to come along and criticize Spain in an ugly and stupid way, you'd be the first to defend it—because you know it and because that would be the only noble thing to do. As John Lennon said to Rolling Stone: I can diss the Beatles, you don't get to diss the Beatles.
However, all this subtlety is lost on the internet. Your comment isn't what it appears to be, but that doesn't matter, because people will react to it as if it is. If you post like this to HN, you will start a flamewar regardless of how much complexity is behind the message, and this will damage the container just the same as someone posting out of ignorance and prejudice. So we need you not to do it here, to protect the community. You're welcome to share your experience in other, more personal and substantive ways, if you choose.

p.s. These are arcane details, but it's interesting to me that https://news.ycombinator.com/item?id=22673470 picked up on the overtones in your comment. Family members (speaking metaphorically) can hear these things.
