What is the deal with pornstars?

I have a problem with them. && their family and friends. Why do they like selling themselves on the internet, and posting videos of them sucking a dude's cock...and still manage to say stuff like "My grandma ia my hero" or "I love my family." Don't their family members have an issue with the wrong road they have taken? Don't they care one bit that they watch and DO porn? I have even seen a porn star say they are a proud Catholic! What is the deal with these porn stars...why do they choose to be one, and live their life and study in college, and act as if it is no big deal to sell their virginity and do dirty things? Why don't they see the terrible things in their actions?? Why d ont their families see the terrible things in their actions? :-/ My theory is, if they really were close to their family, they wouldn't do this, because they know their family wouldn't like it very much. I'm not critisizing, I'm questioning, dur.
