Like a lot of things I suppose I would say that it depends. I think that it is OK to question if someone is being really charitable or helpful to you when they suggest that they are being so, in the context of what is otherwise a put-down. On the other hand if someone asks a question about a scientific theory and has his or her motives for asking it scrutinised simply because the question implies doubt, then I don't think that's OK.
