I'm not sure how did you come to this conclusion. The comment says nothing like this...?

I am saying that the term "human sacrifice" is rarely applied to European rituals of sacrifice involving humans.

You can use the term all you want, try to not use it in a biased manner.

Often depictions of human sacrifice in the Americas are used to justify the exploitation of the native people of the Americas.

It sounds like you’re advocating stretching the definition of the term to support your own bias, when it has a pretty clear meaning.

So when superstitious Europeans kill their own for religious reasons in a ritual to please their god, that's not human sacrifice? Change my mind.

I understand what you mean. Christianity can be seen in a different light if we recognized it as being centered around human sacrifice to a monotheistic god. But I think the problem has more to do with too much veneration for Western religion than it does with biased labeling of Native American religious practices.
