>>96951492To paraphrase, because the word gets thrown about so much and applied to so many different contexts (everything from dragging a child into an ally at knifepoint, to two students getting drunk, to a BF not getting verbal permission from his GF each time) then it basically reduces how seriously people take it. It also equates bad decisions to seriously fucked up situations.
Basically, we use the same word to many vastly different concepts that are often only loosely linked. Same thing is happen to other related terms, like sexual assault, sexual harassment.
