Why should audiophile deniers be allowed on an audiophile forum?

Free speech!!!!!????? Really? I didn't see anyone stand up for Millercarbon's "free speech"! Some have pointed out his poor manners. Yet these deniers have  some of the worst  manners.  They mock, ridicule and implicate that those who HAVE heard the tweaks are a  liar. Then others pile on with their offensive behavior until the whole  thread gets removed. Perfect Path Tech always gets cancelled for that very reason.Nano-flo gets the same treatment now.  As I said in a recent thread posted by @Hilde45, when one man's ox gets maliciously  gored, it should be an offense to all. But that doesn't happen today. Most only feel offended when it is THEIR ox which suffers the gore. Like children on a playground, they often laugh when  someone who they disagree with has their ox gored. As my old step daddy used to say, "right is right and wrong is wrong no matter WHO is doing it. Free speech comes only when THAT rule is applied. true freedom demands justice for all and NOT just those you like and agree with.

As @emailists  has said, (my edits)

It’s fine for someone to post they tried a product and it didn’t work for them, but to dismiss entire product categories (when you have absolutely NO experience with said products  is not a (valid) discussion that belongs on an enthusiast forum.

 Even so, I don’t like stifling someone’s opinion. They have a right to be wrong. But I get tired of the poor ethics & manners of those who call someone a liar without adequate cause. How would you go about proving they are a liar? You cannot. And in the  real world you may be liable for slander or a good old a**  whippin”        
Not only is this extremely poor manners, but it goes against the forum rules also. It  should not be allowed. As to the free speech issue, it DOES NOT apply to a business.

I’m glad that @emailists  has posted this because it has been on my mind for some time. Many good & knowledgeable people have left because of these poor manners which are allowed by Agon. I remember when every post had to be approved by the moderator.  I didn’t like it then nor would I like it now. But when you are in charge of a nursery, you must keep a close watch.. What a shame. Grown ups , some with advanced degrees, acting like impetuous children just to get their way, no matter who gets hurt.

Friends, we are getting far afield from the original post which was about people who's seeming agenda is to be disruptive rather than helpful to the group. Yes, individual rights are important. We should be allowed to criticize. But criticism of something you have NO experience is invalid. It becomes even more invalid when you imply that someone is a liar, based solely of some idea you have without any experience with that item or others based on the same principle of operation. Then it becomes more ridiculous when you imply that science backs up your assertion,  all the while not having done one second of observation yourself.  The same applies when you base an opinion on scientific inquiry which has never addressed the validity of said product. But it gets even more ridiculous when the skeptic is backed into a corner where science cannot rescue him/her who then says that science is ever changing. Well duh! You cannot have it both ways. But they try because its not about finding truth. Its about submission to their rigid rules  Scientism where they have deemed truth to align with their thinking only. Then they call on free speech when they are called out as if they do NOT attempt to shut down every opinion which they disagree with.!!

So the problem again comes down to who's ox is being gored. This is where the double standard comes in.  Many will willfully gore someone's ox because they disagree with the owner of the ox who like the color of his ox. . Yet they often cry the loudest when their ox gets gored by the other in  a defensive move. Kinda like they are crying due to the OP.

Free speech CANNOT be sustained where double standards become the norm. We see this in our society at large and of course that has spilled over into everyday life. This is the offense which the OP, myself and others are pointing to. Its NOT the Opinion which needs to be silenced. It’s the childish double standard in which the opinion is expressed.  A child may be broken of such offensive mannerisms and taught better.  But it is reprehensible coming from grown people. And the offense is further exacerbated when those who are offensive, try to justify their treachery and act as if they are the victim, when in fact, they are the aggressor.. So again, Share your opinion, but do so without being offensive
FWIW I don’t need to agree with someone to respect them. If you teach me something you have helped me. That is a friendly move. But when you slander me and call me a liar, when you have no proof  is far from being helpful to anyone. And is against forum rules.
