Etymology: "Destructivist" is a plain formation: the adjective "destructive" with the suffix "-ist", which marks a person who adheres to or believes in something. Put together, it names someone who believes in destruction, and it can also work as an adjective describing that outlook. The word "destructive" itself comes from the Latin "destruere", meaning "to pull down" or "tear down", built from "de-" (down, away) and "struere" (to pile up or build). So a destructivist is, at root, a believer in the tearing-down of structures, the reverse of the building that the Latin verb's second half describes.
