I didn't find anything you said offensive.
I think again, you have to consider the fact that the film has been shown on TV for decades. A lot of people grew up with the film, and as I mentioned I tend to think there is a certain fondness for things we grew up with.
I still say however, that I think you are over-estimating the film's power...it may have it's fans but it is not some nation wide cult thing. There are popular culture references to it, yes but again as it has been shown on TV for so many years I think that was bound to happen.
