Well, I suppose. For that matter, I suppose there are also pilots who don't bother with the details of altitude and barometric setting as the only altitude that really matters is 0 AGL. While I appreciate their philosophic point, pardon me if I don't fly with either group! I have no problem labeling "speed" as "ground speed" of course I just worry that he knows pilots and instructors who could confuse it with airspeed. If I climb in a plane with a pilot who looks at his GPS and says, "Gee, I wonder if this is my airspeed or ground speed? Oh well, no matter." I'm getting out! :-) thanks for the reply.
