Dear all,
There's a chance that the two of you are operating with different notions of "macro-languages." Within Indo-Aryan, the languages that Alekandu Das mentioned are (I think) ones that are spoken by a relatively large number of people, which could be understood as rendering them as "macro." I don't think, however, that they belong to a single linguistic subgroup within Indo-Aryan. For example, Punjabi and Bihari belong to different linguistic subgroups of Indo-Aryan.
For that reason, if looking for European parallels, one could point to regional languages with a large number of speakers vs. smaller ones, e.g. Spanish vs. Valencian. This is not to suggest that the situation is completely parallel, just to try to sort out what is meant by "macro" — I don't think it's defining characteristic is linguistic affiliation.
Best,
Dieter
