Yeah, you’re honestly way out of line here.

Being correct is not a virtue. Other people are not impressed by how correct you are, or by how great a job you’ve done in correcting others.

Knowing more than others is not a virtue. Literally everyone knows less about some things than others; there is no super genius that is right or most knowledgeable about everything. For that reason (and many others), lack of knowledge is not a good reason to treat someone poorly.

You obviously care about the mechanics of clear communication. I believe that you can be better than this, that you can keep in mind why we communicate, not just how. You obviously know a lot about certain topics as well. I believe you can be better at how you demonstrate your knowledge. This time you showed off your knowledge to shame someone else. Maybe next time you could show off what you know by sharing it with someone in a helpful way.

Then people really would be impressed.

Wow, what the fuck happened to you to make you like this? It’s a post about a map.

Wow, you’re an asshole. Many borders are (or were) defined by positions of natural features though, so no you’re wrong. They aren’t completely made up by us. They are made up, but based on nature.

It’s called a synonym. Get yourself a Thesaurus and read it.

I too would avoid being the team with you, considering your commitment to being an asshole.
