It happens when people are treated as second class, or for that matter, third or fourth class citizens. And it's wrong and repulsive
SP's are someone's daughter, sister and/or mother.
And it's why when people use terms such as whore, hookers, streetwalkers etc it objectifies and demeans, and allows "mainstream" society to see SP's as something less than a real person. And IMHO using such terms reinforces the negative view that mainstream" society has of SP's.
Finally as a closing note, I've been hobbying since July, and all I have had the pleasure of meeting are ladies
