Possibly, but "Cool..." is hardly adding any value, whatsoever. In this case the poster should've simply said nothing unless they had something of value to say. This is sort of the second point I was quoting. There are a number of points in the guidelines that try to get people to add value to the conversation.

Well, at the end of the day you contributed to that with your own comment.

You seem confident about your interpretation...

Does that help you understand?

Agreed. Though in the case of “cool…” there is precedent. For example, John Oliver says it sarcastically¹ with some regularity. Well, he can’t say the ellipsis, but it’s how I’d have written it.

Either way, I’m agreeing with you. People also think that putting a period at the end of a text message is rude², which is bonkers to me³. Soon we won’t be able to use any punctuation without it being considered dismissive⁴.

³ I do it all the time. People get used to it and learn it’s just how I write.

⁴ Yes, that’s a slippery slope fallacy. I’m employing it for comedic effect, not as a real complaint of “kids these days”.

A good rulem of thumb I've found is, if your comment doesn't bring any value and could be taken as rude or flippant, then there's no need to post it. IMO this "Cool..." fits that description pretty well. Nothing to do with "woke" etc. Just doesn't bring any value.
