I think the confusion arises from converting to the 35mm film/FX equivalent.
If you have a 50mm lens on a DX body and you are not likely to ever go to 35mm/FX then IMO there's no need to worry one's self with converting.
However if you were to in the future then use a FX body, then yes you'll notice the difference in your FoV etc, but again IMO within a very short time you'll try and forget the DX limitations
