Some people should simply be ignored. 
Oh, she promptly went on my ignore list after that. 
That's why I mostly just stay in the Varric thread these days. I did poke my head into the romance thread the other night though. I just don't want deal with the negativity.
I can handle it some days better than others, but that thread keeps allowing me to make awesome posts, so I stick around. The key is that I just usually leave the thread and stop posting when I'm really fed up. Other times, it's a chance for me to really be able to speak my mind about something.
For example, if you see any variation of the words, "Sex with the Tranquil," just run. Do not post, do not pass Go, do not collect $200. Just run.
