If you are at all familiar with competitive games of most any sort, then you are surely aware that bad players will make all kinds of excuses or reasons for why "that thing that beat me" should be nerfed/isn't fair. And you would then, presumably, also be aware that nearly all such arguments are flatly wrong and borne out of a lack of understanding and skill. Telling someone that they lack the skill or understanding isn't a non-argument, it's just stating a fact. What they do with it is up to them; scrubs will continue to make excuses, while other players will seek to learn *why* they are mistaken, or what they can do to develop their skill such that that previously unbeatable whatever is now no longer an issue.
