I come to HN for high-quality discussion. If I were looking for snark and meme content I'd be on Reddit.
In this particular case, your parent made a very reasonable case that a web app could simply choose to respect the system light/dark mode and that would be enough. I happen to disagree with them, but they were sincerely contributing to the discussion.
You came along with a 4-word + emoticon + hashtag parody of what they said that was inaccurate and frankly rude. I came away from your comment not at all sure what point you were trying to make but 100% sure that your comment wasn't contributing to an interesting discussion.
Here's a possible rewrite, assuming your objection was that some computers don't support system theming:
> If you only support system themes, you're excluding a large number of older systems that don't have their own light and dark modes. A toggle wouldn't take up much space in the header and would help those users to use the mode they prefer.
I see your point - I suppose it was quite snarky. My take is (and I suspect the same as the people who upvoted my comment) that the comment was disregarding another persons feature request/preferences based because the did not match his/her own. It is an, in my experience, attitude not uncommon - and it (unfortunately) gets my blood boiling every time.
