We were at one point. She was cool. A girl who was totally into SW. We were treating her like a kid sister and some were treating her otherwise. Then she started to become obsessive/compulsive about a few issues (Han Solo, Harrison Ford, Blues Brothers) and she would shoot down everyone's opinions and tell them they were full of crap. She wouldn't even put forth logical arguments. Just "what I say is right and you all are wrong". No matter how many times we would try to reason with her, there was no breaking through her thick skull.

Actually the thread you were reading is not the best to see what was going on. There was a Disney thread a while back. She was downright violent in that one. Dunno where it is.
