This might had been a cultural thing between me and the other party. I don't mind being very to the point and strict about programming but when it comes off as condescending and "I know better than you" it's just something I can't stand. Or maybe a better example, they make pesky remarks on your programming style while ignoring all your writing about theirs. I think because the other person here was a bit older than me, not a senior dev but still old enough apparently, that he felt he had to prove something to the younger guy.

But yeah I'm going off the rails here. My point is that relationships are hard and even in seemingly neutral setting, a code review, tensions can arise. I do not know what to say on those occasions but getting snarkier and snarkier in comments is definitely not the way to go. Bad code reviews have been one of the most infuriating things I've come across my developer career.

As you already said, this sounds like a people issue. Snark, sarcasm or belittling has no place whatsoever in a code review (or at a work setting in general, obviously). Sounds like you just got a bad colleague.
