BabeGirl,
Please keep in mind that most people´s negative comments are often reflections of their own insecurites and ignorance. What do these comments in the chat room say about you, and what do they really say about the other persons?
I´m not familiar with the chat room here, so I cannot really comment on the hyper-link. As for handling your next chat and if these comments come up again, I would personally not continue the discussion. Don´t give judgemental people ammonition to hurt you. Let them know with dignity how their comments are affecting you and then stop a futile conversation. I would use my energy to build a safety net around me with people who understand you and respect you and above all, are not destructive.
