I disagree. In support forums, people can only find what the message contains by reading it. I know we are talking primarily about debate forums here, but the mishavior is found in support forums too and in some of those moderation appears to be very lax. When it comes to debate forums, while there are obvious topics to be leery of for those who want to avoid contentiousness, such as politics and religion, there are also health topics which merit debate where members should be free to safely go to in order to see more than just the favorable post on support forums.
Support or debate, there is no need nor justification for personal attacks or abuse. Saying stay away is in my opinion a cop-out to excuse inexcusable behavior. No member here should fear going to any forum, and they should be able to participate and post in any forum without fear of being abused too. As I said earlier, there are plenty of cess pools on the internet where name calling, slurs and put-downs are allowed. By and large those places are not intended for healing. This one is, and such misbehavior is in no way healing.
