You're right. K/D ratio [i]ad hominem[/i] attacks have been the second most common logical fallacy committed on these forums since the Halo 2 days and stat tracking in console FPS games began. However, the most common fallacy, by a mile, is the anecdotal fallacy (i.e., using a personal experience or an isolated example instead of sound reasoning or compelling evidence), which is the typical method of argument used to start a debate in these forums. For example, "I was killed by this weapon 6 times in one game and therefore it needs to be nerfed." Neither is justifiable. In fact, attacking another user's argument based on their stats used to actually be against the rules, since it is such a distracting and pointless way to attack another person's opinion. But we've learned that these fallacies are not going away anytime soon. Even in this thread, I see people trying to justify why a K/D ratio ad hominem attack can be appropriate if not sometimes, then all the time -- it's completely wrong, of course, but there's no point in debating with them. These fallacies work on this forum because they're provocative and they make other people feel like they have to respond. Which they always do. But history has proven over and over again that the best defense on internet forums against logical fallacies is to ignore them. If see an opinion based on anecdotes rather than logic, reason, and/or evidence, ignore it. And if someone responds to your well-reasoned argument with an attack on your stats, let them shout into the wind. Problem solved.
