that wasn’t a personal attack.
a personal attack would be:
“man, are you just a dick or what?”
what they asked is simply a request for you to explain your motivations, since they seem nonsensical to the previous poster.
(and immediately jumping to “personal attack” when someone is trying to understand you doesn’t exactly imply “peak intellect” either. and btw, your snarky “peak intellect” <-- THAT’S a personal attack. phrasing it as a statement doesn’t make it less of an insult.)
“what’s your problem?” is a common expression. it’s a phrase, it isn’t literal.
