I have not come across that thread yet. Almost all on here keep it respectful, and do not let it get personable. I watched one thread where what you described was devolving into that. A new member who was very opinionated that his way was the only way. I don't think he stuck around. With that said i have only had 2 other instances where it seemed a personal augmentative thought was directed towards me. One I just stopped posting on that thread to avoid any problems, and the other I just used links and direction to justify what I had posted. It is better that way for all on the forum. Knowledge and personal opinions are what drive these threads, and I like to learn from other members experiences.
When your wrong about something, and it will happen at some point, correct it, or edit it for content. Did that, Done that!
"I was un-politely told to get off their thread"..............................Wow. But don't elaborate,.....let sleeping dogs lye!
