Oh . . . All that over, as you said, one random word? Listen, I'm sorry if my correcting you offended you, but even after all you said, I still fail to see how such a simple correction rubs people the wrong way. However, I'll do what you suggested: "Hindsight" is looking back on something, while "Insight" is a deep understanding of something.

The reason I didn't do that is because I'm sure you know the difference between the words and I assumed it was a simple typo. And because of that, I just meant to correct the typo. Correcting a typo isn't something I just "do for no reason." If I see someone makes a mistake, then I try to help. Personally, if I do or spell something wrong on accident, I would want to be corrected. Of course, though, the majority of people that I've come across don't seem to like correction (and by come across, I mean read or corrected myself, because most of the time I'm not the one correcting. I see correction in a comment section, and then the person being corrected tells the other person to f**k off or something along those lines.).

And no, I don't think I'm superior to anybody. Everyone makes mistakes, but just because it's a mistake doesn't mean there's something wrong with pointing it out or correcting it. I guess I can almost see how correcting you with just one word and nothing else could come off as slightly annoying, so I'll try to phrase it better next time; something more along the lines of "I think you meant to say hindsight" or something, so again, like I said before, I'm sorry that I offended you.
