The world is made up of all kinds of people with all kinds of opinions.
Some opinions are important to some people some advice is important to others.
We should respect each other's opinion and not try to shut them down when they post something that may not be helpful to you but will be helpful to others. I think we should all respect each other here and everywhere.
If you are posting in a opinion-based topic, then by all means I agree. There is no reason to be rude.
Knowing the difference between someone calling you an a$$hole, and someone calling you completely wrong in your opinion are two different things. The first is a verbal attack of you that offers no furthering of the discussion, the other is just a rebuttal with commentary of your opinion. The first is rude, the second is not.
So many people are unable to understand the difference.
On the other hand, I've seen a number of posts from you that suggest that you are highly uninformed about AV. You have put forth several posts where you have stated as fact things which are provably wrong. Not just bad opinion. But, bad opinion that you have put forth as 'fact', which demonstrates a severe lack of knowledge of the subject matter which you are making claims about.
It's made worse by the reality that if you were to get a better product and put it head to head with what you are making statements about, you would be shocked at how quickly your statements would be proven as false.
I have had any number of times when I've said things which others have pointed out as being incorrect to me. I hate when that happens, but it does. When it does, I specifically try to thank the person who has corrected me, and I revise my post (if I can) or I state that my previous post was incorrect so others don't get caught up in the bad information that I provided.
These forums aren't about patting others on the back over and over. They are about the sharing of information. That information may very well be opinion, or opinionated ideas. Like 'how to set a room up properly' when it is a weird room. There will be ideas thrown around. Like 'what equipment should I buy', or 'what do you think of my setup'. These are going to have some opinions in them. Some will be good, some will be bad.
Making claims as fact, which are provably incorrect, deserves to be shut down immediately. If nobody calls you names in the process, then it isn't rude, it is just shutting down misinformation. If you continue to post the same bad information, then you will need to perhaps learn that things aren't as you claim.
