To be fair to them, we have our own delusions. For example, SINAD chasers, people who time align subwoofers down to 0.02ms (i.e. me!), people who place too much faith on automated DSP solutions, people who think the frequency response is everything, etc. The only difference is that most of us are open to persuasion and can be talked out of wrong beliefs. I think there is a certain respect that we have for each other, and also for those who know less about a particular subject than we do. After all, we were there once.
