While chatting w/ a friend over prohibition, it occured to me that porn stars are essentially payed to have sex. Granted, it's public sex as a form of "expression", but they're still payed to perform sexual acts. Everyone (mostly) agrees that porn is protected speech, so how is prostitution not legal? It seems that only closeted acts of prostitution are illegal but selling one's body to online lovers is perfectly fine. Would someone care to explain how flagrancy = legality? Or, would someone care to explain how porn stars are not prostitutes? Seems to me prostitution is only legal if you have it in front of the whole world, but relatively private prostitution is prosecuted. Why?
