It’s less touted than Aztecs and Mayans, but it was definitely taught in Amerikab schools when I was younger and I’ve heard the claims semi-recently from people I know who should definitely know better. There are ofc also just uneducated westerners who lump them all together under the banner of indigeneity. I spoke to many indigenous people in Peru who were tired of having Westerners assume their ancestors practiced human sacrifice, is my experience w/ it.
