Hey Miss Susanna!
Whenever I find myself doing something I'm not sure I should be doing, I like to stop and ask myself why I am doing it.
You mentioned that you enjoy posting in News. Sooo.... WHY do you enjoy it? Do you love a rousing debate? Do you feel like it's your one shot at saying what you REALLY think about the state of things? Is it like an escape for you? How do you feel after spending time there, drained or energized? Is it possible that it's ok for you to keep posting there, you just need to work on your tone and civility? (I have no idea if you need to work on those things or not, I usually stay outta the news forum lol).
Anyways, just thoughts!
