Active Greek Members Being Called GDI

How do you all feel about active greek members being called GDI? Does that make sense to use such a term in relation with someone who is already a member of the Greek community? I have heard it use to describe non-greek affiliates and normally it is not offensive when used in that context. However, lately I have been seeing it being used to describe greek members who other greek members feel are not group oriented. What do you all think of this?
