Yes, there is. Vide my last sentence above.

Proving that is futile because you want to argue anywas and as I said I'm not that eloquent.

Nobody takes away from SPJ of what he is.

Edit: you expanded your argument after I wrote above. I don't feel like I have anything useful to say. Not that I felt that in the first place, I just gave a counterexaple showing of how world stands. Next time I'll run into someone I'll first ask what school he attends and who is his advisor instead of arguing about what he semantically meant describing his field. Then it would be evident what he works in and if we have anything to learn from eachother insetad of wasting our both time for idle argument.
