I think this is relevant since it relates to PETA's beef with AC4:
"History is our playground in Assassin's Creed. Assassin's Creed IV: Black Flag is a work of fiction that depicts the real events during the Golden Era of Pirates. We do not condone illegal whaling, just as we don't condone a pirate lifestyle of poor hygiene, plundering, hijacking ships, and over the legal limit drunken debauchery."
Just because you enjoy something that isn't real doesn't make you want to engage in such acts. You're not 'tsundere' to anime, you're just a little over your head on it. Find some air, get outside and take your mind off of anime for awhile.
