All of HN other than you isn't actually one person arguing with themselves. There are a variety of people here with a range of opinions, each with different degrees of internal consistency. This smacks of the "everybody says all kinds of things, so you should just ignore everybody" or the "they're yelling at me from the left and from the right, so that's proof I'm doing everything correctly" defenses. The second is the moderation fallacy; the first might be called the "Argument From Sociopathy."
