That doesn't mean that everyone unanimously agrees.

Yes, that may be. And yet, out of the thousands of Reddit threads I've read, you're the only person who has ever complained about it. Others have asked, and then when told go "ok that makes enough sense". And more still were able to figure it out on their own since it's not that complicated.

I can tell people that it doesn't make sense, or block them if they keep doing it just to be rude

That's not what I meant. I was pointing out how you are never going to be able to change the tide of 100 million people.

I'M not the one being a dick.

Acting like you don't know what it means when people have told you before IS rude.

I'M not the one that looks stupid.

Acting like you don't understand this incredibly simple thing does make you look dumb. I know you're not dumb. But you seem so intent on appearing so. That's all I'm trying to say.

Because everyone that uses a computer understands programming language, right?

That's literally not what I said. I was giving you the history of it so you might understand it's not arbitrary. I THEN even went on to show how someone understandably not familiar with that history could still figure it out.

Based in zero context other than an arbitrary letter that could stand for just about anything

No, based on basic social skills and the context of the thread the comment is in. The comment isn't in a vacuum. They can read the sentence and understand it was probably sarcasm. Then they see the s, and can understand what it stands for and that it's confirming their gut feeling.

I'm straight up just trying to help you out here by giving you the history and how it's not arbitrary. By helping you understand how others are interpreting your actions. It seems I may be wasting my time though, as all you wish to do is be combative and downvote me.
