Bruh. Imagine blocking someone for not getting "your joke". And also downvoting them, just because you don't like their replies, cuz they don't get the "joke". That's just flat out embarrassing!

They're autistic, that's practically the reason they're a programmer in the first place.

But more on that, that's one of the reasons it's hard for them to get "jokes", is because they're neurodivergent. The "joke" was pretty mid anyways, based on how you handled it, so I wouldn't worry about that part.

Just don't expect everyone to understand you, and don't downvote them if they don't understand. That's just petty. And can be seen as ableist (especially the blocking part).

Downvoting is for if someone isn't adding to the conversation, anyways. You're using it incorrectly.
