The correct term today is ancestral puebloan. Anasazi basically means "ancestral/ancient enemies" in Navajo. Anyway, that debate (to the extent it existed as a general thing) has been resolved. It's both. Violence, including burnings, is archaeologically well attested at numerous sites. Likewise, ritual destruction is both archeologically and culturally well-supported. There's debate about many particular sites, but even many of the smaller debates like man-corn aren't subjects of serious disagreement anymore.
