Earlier quoted context omitted.
Which bit to you find disturbing? The fact that the game acknowledges the existence of hookers, the fact that the game draws attention to the fact that many hookers work out of pretty seedy bedrooms or the fact that the game draws attention that many hookers end up looking less than their best. Would you have preferred "this is the hooker's fabulous bedroom. The bed's perfectly clean, so is the hooker!"
Try not to use begging the question as an argument. But what makes me sad is the second part. Because it's in a game, and it's done to be funny. I'm not shocked by the existence of hookers. I should be, but I'm desensitized.
I'm not saying it's a nice job, but neither it is fixing sewage pipes. You should be shocked that pimps exist, maybe, but then again their role is quite natural and I'm sure some of them are quite the professional. The massive amount of abuse surrounding the "industry" is a problem, but it's hardly the only industry where management can abuse the workforce.
