If you had a pacificistic animal-rights activist barbarian character in my game, I'd point you toward the door, but that would have been covered in session zero when game expectations were set. You might want to explore those things, but I really don't, at least not in my D&D game. My 7th Sea Hack for Firefly, sure, sounds fun, let's do it.
Right, if such a character is incompatabile with the campaign then the DM should have just banned it out the door.
