Even though I don't like PT, I consider myself a kind of common-sense Star Wars fan. When it comes to EP4 title I don't see why someone who accepts the rest of the saga (whether that is just OT or the whole thing) would insist on calling it just "Star Wars". Well tbh I actually know the stupid reason... you think you are being "cool" for doing that but quite frankly no one really cares.

The only case when I think it is reasonable for someone to stick with just "Star Wars" is when the person ignores the rest of the films (including ESB and ROTJ)... like Anchorhead for example.
