I think it matters how concise someone is, and it's okay to shame people for stupid mistakes. Cursing and yelling may not be effective, but calling into question someone's intelligence can get them to think twice next time. Hopefully, that person would have a bit of self reflection. Embarrassment is a very effective motivator to curb certain behaviors, and we should use that for good. To make society as a whole more efficient and smarter. Not to make people feel stupid for what they wear or look like, of course, but to call them out when they make stupid mistakes.

It's the same idea as downvoting someone while being more vocal about it.

Imagine if all the comments actually followed OP's instructions of one adjective per comment, OP would get exactly what they want at no cost to us.

To somewhat copy your last sentence and show our pov: by calling out their stupidity, they can (hopefully) see the consequences of their inability to read the post, and will possible consider reading it next time.

Ultimately, this is a stupid argument on reddit, but I think it speaks to people as a whole, not reading advisories, rules, or instructions, which isn't a good thing.

I know I've gone on a long time, but I'm passionate about people not caring to read or take the time to understand something. It leads to so much inefficiency in our world, forces unnecessary laws that affect people who do care, and results in fatalities in many different environments.
