As I said before, you have to give them time. It's not really something to get personally offended over. There are a lot more serious things you should probably have your mind on - perhaps not even Tolkien-related. I mean yes, having someone claim to know more than you about Middle-Earth when they know about as much as an earthworm does is annoying, but it's really easy to either just ignore them or kindly correct their knowledge with proof. I typically do the latter, pointing to textual support for whatever comment I have made that they refute based on one bit in the movie. It's impossible to contradict that. And if you do find their lack of knowledge as annoying as you seem to, just don't talk Tolkien with them.

And also, if a person's only seen one of the movies, they obviously didn't care for it, or they probably would have seen the others. Usually their comments will probably be derogatory anyway, even if you tied them down and forced them to actually read the books. Not everyone (even if they understand it) likes Tolkien. There are perfectly intelligent individuals - certainly more intelligent than I am - that will admit that Tolkien's style just isn't their cup of tea, so to speak. Whenever someone doesn't like something, it's much easier to find fault in it. Even if it is a good piece of literature (and regardless of content, the movies were well-made), if one doesn't like it, it's difficult to compliment it, even if the good points are staring you right in the face and calling your name.
