Do they? Or I mean do we?
Not very often. You are right that the happy hooker brigade bring up the topic most often.
But occasionally, children will be told that they'll have to flip burgers for a living if they don't work hard at school.
Most people do want higher education for their children, that's an increasing trend. So people in unskilled low-wage jobs would have just as much reason to complain about being "stigmatized" as "sex-workers". But I haven't heard that happen, ever.
And ... how often do people - average people - talk about whores, really? We are told that it is "social stigma" that makes punters attack whores, but when you look closely, punters are the only group of people who talk badly about prostituted women, happy hookers and trafficked rape victims alike, on a regular basis.
I am not a conservative woman, but I highly doubt that whores are a common conversation topic among conservative women, or conservative men who are not punters.
Libfems talk about prostitution being a choosy choice, which allegedly is a good thing.
The only other group who talks about prostitution (and the only one that is accused of "whorephobia") are radical feminists.
So, if we are to believe this "whorephobia" theory, punters hear radical feminists talk about how they want to abolish prostitution, somehow conclude that they must hate prostituted women, and ... love the radical feminists so much that they obediently go and kill some prostituted women to do the radical feminists a favour?
It is just utterly illogical.
