Whart hit the nail on the head. The internet has brought a whole new way for people to communicate, audiophiles and others. In the old days, it was done face to face so treating others with respect was usually the way to go. Now it's done hidden in a cloud without any civility restrictions whatsoever. And the weak minded usually takes advantage of the situation. What an easy way for them to get even with all the people they can't deal with in real life. It's liberating.
I chose to ignore them. Still a lot of respectful posters on here. It's really easy to differentiate them from the fakes. It sure is an adaptation challenge for us in our seventies, but I'm always up for a challenge. Heck I'm an audiophile! :)
