On first joining this site a few years ago one of my first interactions was with this one guy who I first thought was sincere but misinformed. We do such a lousy job teaching science and I thought that's all it was. Immediately though it became clear this guy was not at all earnest, he was in fact using what little knowledge he had to insult, confuse, and demean.
This was my first time coming across a bona fide psychopath and so rather than leap to that conclusion I did a little web searching to try and prove the guy wasn't as malevolent as he seemed.
No such luck. What turned up instead was a guy who met him at a show and said he enjoys mocking, tricking, and ridiculing audiophiles. But that was just one guy, so I kept looking. Turns out he also has a website that deserves a Guinness World Record for word salad and audiophile mockery. Although I fail to see the humor in charging a grand to improve your system with a phone call.
Since then I have seen a number of these, sad individuals with nothing better to do. Well it is a public forum. Like a sidewalk in a big city, you are going to have to walk past the occasional howling mad. A good metaphor. When you see them, look away. Do not engage. Nothing good will come of it.
Walk on by.
