I believe that if the social currency is interactions instead of specifically positive interactions, as well as with the shift from "dislike" to "disagree" (something less associated with negative emotions) this would discourage engaging at all with strongly offensive content, effectively just starving it of attention. Of course this is just a theory; until someone implements it and evaluates the result, I may well be completely wrong and maybe it'd even have the oposite effect.
