i've been giving some thought to the problem of disagreement and discussion, hence the question: how open are you to actually arguing for your views when someone disagrees with you? what about *discussing* them?
as for me, i do think that there are certain things beyond discussion, like religion. other than that, i've come to think that at least a minimal commitment to conversation requires some attempt at justifying/providing a genealogy of one's statements, as opposed to simply inflicting them on one's interlocutor. 
i had this discussion with my stepfather recently and he was saying that one can have vastly different goals in engaging in a conversation: either willing to open one's own views up to a challenge or convert the other person, to "sell something." in a way, i don't think it (the problem of intention and sincerity) matters all that much in this context. even to sell something is to comply to certain things and to temporarily inhabit the conversational space, which is all i'm trying to say.
