I grew to love Joe Lauzon. Maybe it was based on pure appearance but I always had a weird sense of dislike for the guy but once I realized how down to earth and intelligent he is, it eliminated anything negative I previously felt about him.
I grew to hate Rousimar. I always ruled off his mistakes based on him being really stupid but he never came off as a douche to me. Now it's all very clear that not only is he as intelligent as a salmon, he's a dirtbag.
