Erik,
Wait...you mean you experienced personal attacks just by daring to question accepted audiophile dogma about items like power cords?
Welcome to the club.

Agreed. People should buy what they like.
We also shouldn't feel personally aggrieved if someone else doesn't immediately accept what we ourselves believe. The first things an aggrieved audiophile will attack are the old "ears or gear" - "well, clearly you don't have the acuity to hear real differences" or "you must have substandard gear."
