Mark, exactly what i had in mind. Bravo!

The worst are, as you say, those who've never heard a speaker (or whatever), and say they know everything about it and nothing will change their mind.

same mentality as religious fanatics (ignoramus)...they have caused wars for thousands of years because of this kind of behavior.

what everyone should do to counteract this is by not answering the BS;
and the "golden ear" experts should study human nature/psychology a little.
