I sometimes use this icon to be ironic and show off Karin's badassery, and sometimes I use it for shipping. It all depends on the situation. I actually used to ship Karin/Suigetsu much harder than I do now, but that changed when I became utterly addicted to Karin/Sasuke. I still ship them on/off, though. (Actually, the truth is that I ship all possible combinations of Team Hawk. ALL. POSSIBLE. COMBINATIONS.)

Truly, I agree with you on an intellectual level, and Ao having the Byakugan justifies his sensory abilities much more than that random guy chatting it up with Danzou, but I had already decided to be unimpressed with Ao, so I wasn't about to change my mind. -_-;;
