From my experience there is a real issue of C and C++ developers treating undefined behavior as an error. Yet you can't reason around undefined behavior, you can't catch it at runtime and there are more ways how UB is meaningfully different than an error or bug in the program logic. I can see how such a post could inadvertently reinforce such a mindset. No clue if the person you are responding to had that in mind.
