I appreciate what you're writing about demoscene programming, but the GP comment does not seem to me to be shaming. It most likely was just about the commenter not having time themselves. HN has a guideline for cases like this:
"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
I agree with the rule, but I only accused him of shaming after he drew a broad insulting caracature of a community I'm involved in and actually understand (the demoscene) by suggesting that it just involves people "browsing early 2000 forums and installing gentoo on PS3s". I think if you said that to any demo coder they'd tell you to eat sand. It's not even remotely close to what that scene is about. If there's a criticism to be made here, perhaps it's about not making assumptions about groups you know nothing about?
I made no assumptions other than what he explicitly said, which was insulting and displayed ignorance of a community he clearly does not understand. My original comment was also only "People who care about their craft?", which was simply saying that people get into demo coding because they care about doing something worthwhile (getting the most out of their machines in an artistically satisfying and interesting way).
There's a common social anti-pattern in most tech forums of hand-waving away any complex domain knowledge that the person doesn't personally use as "useless". I have no regrets about stating the contrary.
I am amused that I am the one getting a warning about this though. I'm not the one that made a drive-by ambiguous comment that could easily be read as singling out a fun community as being a waste of time. I just pointed out that that's what he just did.
I see now that the problem was that you pointed it out in a way that made sense to you, but not to the rest of us who lack all that background information. If you had responded in the first place with the explanation you've posted here, it would have been much easier to understand what the issue was. Now that I read this, I get your point, and I also see how the problem started with the GP comment, not yours. But this was not at all clear to me before! and I'm sure not to many readers.
HN has been super impressed and favorable to the feats of demoscene programming for over a decade now, so hopefully there's a lot more of that than this.
