There's a difference between sex worker and prostitute. You should know that.Nothing in that Toronto Star story validates your claim. The newspaper makes no reference to the "class" of the lady in question, simply refers to "an apparent prostitute" and notes that the police report includes "rumors that Ford has used escorts or prostitutes.
I fail to see how this becomes a class judgement on sex workers
There's also a huge issue of buying media and of calling an unknown woman a prostitute with zero evidence under the guise of quote.
Be a little less blind.
