I dunno which forum you’re looking at, but most of the replies to any worthwhile thread are usually constructive in some way, albeit a bit abrasive.
There are a few curt or meme responses, but not nearly enough to suggest a majority.
Well it also stands to reason that when someone gives you worthwhile advice (such as on how to avoid toxicity), you don’t immediately turn around and start to unleash the very thing you claim to be against upon those individuals.
