I did encounter a very sour group on a certain subreddit somewhat recently haha. But then just yesterday I was searching something online, found a relevant Reddit post through Google, and found a comment thread where two people were tearing each other apart for no reason other than a slight disagreement. It wasn’t a “hmm, I don’t think so.” It was a long chain where the further you went, the darker, meaner, and snarkier it got. Wish I remembered it right now. That’s what got me thinking and making the meme. But yeah, maybe my own experience planted the initial seed.
