I think this is a fair point. However, it seems to add more ammunition to those who want to maintain differentiation between Drum Corps and Marching Band. Regardless of the reasons, it doesn't make sense to look for more and more ways to make the two unique activities more similar.
My point was that the results of those questions don't add ammunition to any side. They're poorly worded and vague, there's no way to really extrapolate what folks meant when they answered the questions.
