Am I too big of a jerk,even for audiogon?

Being a jerk is a byproduct of narcissism, aptly demonstrated by this thread.

I notice the real jerks have not posted to this thread.
Possibly because they cannot sell anything.
This is progress and very refreshing.
Long may it continue (he said, in hope and not expectation).

I value the OP because he starts interesting threads, and unlike some he can answer what others might perceive as a Dumb Question with succinct and non judgmental answers.
  It seems as though he might be having a crisis of confidence.  His subsequent posts In this thread quote only his detractors, not people who are supportive.  On lively threads if you stick your neck out there will be some return fire.  The OP seems bothered that there are times when he gets sparked up in a discussion that he makes some posts that he subsequently, upon reflection, wishes he hadn’t.
At least he recognizes this, and I remember several times when he later takes something back, and that’s cool.  The worst thing imo is when people refuse to admit error and double down on their original mistake.

People need to get a life, work, volunteer, do something !!
Read enough to establish the futility of this post.
