The GP comment may have been bad or wrong, but it didn't break the site guidelines as far as I can tell.
We need you (i.e. everyone commenting here) to follow HN's rules regardless of how badly other people's posts are. Moderation is inevitably inconsistent because we can't see everything; not even in the same thread.
And there is nothing snarky about this. We've seen this exact scenario happen recently in certain areas of the US (e.g. Oregon) and Portugal where they eased off on criminalizing drugs use. You're talking about an economic weak group, where legality is less of an issue than cost. Them being 'homeless' is BY DEFINITION an indication of their poverty.
If you still want to double down on considering my post 'snarky', how can you also not say the same about 'https://news.ycombinator.com/reply?id=39580412&goto=item%3Fi...' in this very thread.
