I think many of us throughout the years been reading pjmlp's comments which fits a certain "theme". I don't mind though, it's just text after all, but was hard to keep myself from entering the meta-conversation when the opportunity just sat there. I still don't mean no harm by it, we all have our less agreeable ways of writing our comments, I'm surely guilty of it in some way too.
You can express annoyance at someone's pattern of behavior without it being personal. embedding-shape isn't the only person annoyed by pjmlp's repeated disdain and snark towards people who use C (or Zig or WebAssembly or Rust or...).
