I agree. Only a person who is insane can spend considerable time there.
I guess I've just been diagnosed as insane ;-)
When the leader of a forum states that "I know all I have to know" to begin a discussion,
I don't know where that quote comes from, but in any case it's cherry picking to seize on one thing he (or anyone else) may have said at one point, to ignore all the other reasonable claims and tests he has produced. THAT is a form of motivated self-blindness in itself. It's like twitter-think.
I've heavily disagreed with Amir on a number of issues, but see that on other things he has made a very good case. Someone looking for an out will seize on something Amir said they don't like. Someone interested in truth and intellectually honest conversation will have a wider view and note there may be "good" with the "bad."
that is the time you know that it's a closed forum and nothing can be gained by spending time with them.
What do you think of someone who insists his perception is so reliable he can not be wrong? That is essentially the basis of the Golden Ear cohort of audiophiles who push back on every single argument/measurement/counter-evidence with the claim "But I Know What I Heard So I Know What I Know And You Can't Tell Me Otherwise!"
How much do you expect to gain from that?
