If you work for a gun factory, do you tell your friends? Even if you keep its databases up and running? To friends that don't know anything about computers? If you keep the servers running for a tobacco company, what do you say to your kids when you don't want them to smoke? If you work for Microsoft, would you admit it? Would your wife lose respect? If you work for a pharmaceutical company, do you tell your date? Do you still tell your date after she told you her kid sister is handicapped because of some side-effects of some medication her mother took while pregnant of the sister? Do you tell if you work for the car industry? The oil industry? Venture capitalists? Do you tell that you worked for Enron? McDonalds? Amazon? SCO? A logging company? The CIA?
If you shy away from working in the porn industry because of its tainted name, where else would you not work? And if that's a rather short list, wouldn't that be hypocrite? Did I write a sentence that wasn't a question?
