Edit: What was here was a cruel and specific piece of satire that's served its purpose.

In short: if you were reminded almost every day that you're not quite like everyone else here and if that difference were the focus of countless jokes, you might get tired of feeling singled out all the time. It's not about just one joke. It's about a culture that can't seem to stop focusing on the irrelevant things that make you different instead of the common things that the community is, ostensibly, about.
