This term used to have very distinct meanings. It was a narrow definition that consisted of things such as violent serial rapists, child rapists, and sexual murderers. Now, the term is used to encompass things such as staring at someone too long and a wide wide assortment of other behavior. This means that instead of a narrow variety of people being encompassed by this term, it is rather going to encompass a near majority of the population, as a majority of people have done some sort of unwanted sexual thing at some point in their lives. What this means is that instead of the average person understanding what you mean by sexual predator they may soon not quite understand specifically what you are talking about. How did this term encompass pretty much everything?
