I laugh at the phrase "dishonor the family." I really couldn't care less if my daughter (or hell, let's cover our bases here, son) became a porn star/stripper/Hooter's waitress. Those are legit jobs in legal industries and if they're of legal age, then it's their decision. I may try to put things into perspective, though. Say my daughter wanted to be in a porno because she thought it would make her be "beautiful" or some similar thing. I'd tell her the cold, hard facts - that men only watch it as a ******bation aid - and encourage something like modelling. But in the end, I wouldn't excommunicate or punish her at all.
