I'm not sure how it's a personal attack, it would be like someone who bakes bread for a living saying that the tolerance of products doesn't really matter, compared with a machinist who knows exactly how much it can matter. It's quantifiably true that serious QA is a thing, your industry just doesn't have it. If you choose to turn that into a personal attack I think that says more about your internal state than it does about the actual post I made.
