I suppose, although the normally I'm not would mean not hearing it so often that it becomes a well-known identifying personal tic.
I don't see the contradiction here.
I interpret these kind of phrases as: "I don't like to be rude, and normally I'm not, but in this case I need to make an exception."
Frankly, not everybody actually meant to say that, but this interpretation still helps to deal with those situations in a civil, non-escalating way.
