This answered directly to a comment attempting to differentiate religious from other imperialist practices. I can only see "aboutism" in this, but no "whataboutism" – that is, maybe in those arguing it may be just like any other argument they do not appreciate.
Read the whole thread. The human sacrifice was being criticized. OP did a knee jerk “like all the empires” and got a reply pointing out that many had banned human sacrifice hundreds of years before that.
OP then changed gears to include completely different reasons for death to make it seem like that made human sacrifice no different. Textbook whataboutism.
