that's a good question and if you lead with that it would have been a genuine discussion but you had to slap the "savage mythologizing" in the comment and what did you base that upon? the excavation that has been done points to a direction, is it a really significant evidence, no but its not nothing and it points to the possibility that IVC was rather less barbaric than the other civilizations and this was prior to the study in TFA which is even more evidence in the similar direction!!! so it seems to me that you are raising suspicions based on strong bias that you have against this region rather than any genuine curiosity or scientific backing.
