I have only been reading this Forum for a very short time and this is my first posting. Depending on the response, it may be my last.

I’m glad you’re having this discussion and please allow me to offer my humble opinion and perspective as a newcomer. 
My very first read was about an article that appeared in the NYT about a high quality vinyl producer from Britain. The discussion, from the very first reply, quickly disintegrated into a rant by one individual, using thinly veiled memes from one political side, into a vehicle to disparage the Times in general.

I thought to myself “Hmm, maybe I should go back to reading Vinyl Engine or Audiokarma...”

You guys do have a problem at Audiogon, and you’re putting off newcomers. Whomever moderates this site needs to get more involved, pronto!

People make the world go around.                               vive la difference.

Could everyone Please stop talking about me, I Am sorry to whom I offended  🙁

I am not wise enough to judge where to the draw the line between allowing free speech and restraining internet bullying.  I would not want to have the moderator's job. 

That being said, on this forum I made the mistake of repeatedly engaging with someone who displayed what I now understand to be virtually textbook narcissistic behavior.  I watched some YouTube videos on narcissists and it finally clicked.  
 
Nnicola, welcome and thanks for sharing your perspective as a newcomer.  You'll have to wade through unhelpful posts from time to time but imo it's worth it, and if something really seems out of line, use the report button.
