It's not "off" unless you're simply reading it literally. If you do that, then it's a verbose way of saying "I agree". But the connotations are something like "I agree, strongly, and in particular am implying (possibly just for effect) that there are objectively right and wrong answers to this question and the other answers are wrong." The main difference is the statement that there is an objective answer to what people may be treating as a subjective question.

If it helps, you can think of it as saying more about possible disagreeing opinions than about the specific opinion expressed. "This answer is right, and the people who disagree are 'objectively' wrong."

It took me some time to catch on to this. It can certainly be jarring or obnoxious, though sometimes it can be helpful to say "yo people, you're treating this like a subjective opinion, but there are objective reasons to conclude X."

It's the first time I've ever commented that, and I was trying to figure out a way to omit it. I don't like that sort of phrase either, I especially hate comments that just go "This.", but they're rare on HN so I'm in good company.

Ultimately, I put it because:

- It was the most directly informative comment on the thread;

- It had been downvoted (greyed out) to the very bottom of the thread; and

- I wanted to express my support before making a fairly orthogonal comment without whiplashing everyone.

The whiplashing concern is the problem I run into most generally. It can be hard to reply to someone with a somewhat related idea without making it seem like you're contradicting them, particularly if they're being dogpiled on with downvotes or comments. I'd love to hear other ways to go about this, I'm always trying to improve my communication.
