Damn, this thread made me realize a lot of people take porn way too seriously...
It's a business... hot girls will fuck ugly guys (and some good-looking guys) with big dicks for money, and a lot of people will pay to see it. It doesn't mean female pornstars are necessarily bad people; hell, I'd gladly fuck for money on camera. It just means if you drop an O-ring defending porn stars, you need to take a step back and re-examine your involvement in real life. Porn stars are the objects of public fantasy, and thus the consumers will treat them as such.
Don't have an anyeurism defending them; people do the same thing to every public figure from Obama to Hilton. Get a grip.
