Axe to grind know it alls

Recently I have noticed that there are people who apparently enjoy having controversial posts. One in particular stands out. I have no problem with people expressing different opinions but are they doing this just to get attention? They don’t care what the responders to their posts have to say as only their opinion is the correct one and everyone else is wrong unless they agree with the op which is rare.

I have always looked at the Audiogon forums as a resource to get information and exchange ideas . When the post is a one way street, I think it does little if anything to contribute to the forums so going forward I will just ignore their posts.  Anyone else irritated by these posers?
