As much as I (at first) agreed with celeb gossip sites leaving BK alone, I realized she also has a decision in it. Now that there will be an interview with Oprah airing, I think BK wants to be a celeb and will have to deal with it all, and realize it is via her choices.
If she were not doing an interview and any potential future interviews, or any ustreams, twitters, facebooks, etc to get herself out there, she would be able to fade into society as a just another star's offspring. That is not the choice she is making, so now she will be stuck with the good (which could only be $$$ unless she has some hidden talent) and the bad. She was raised in the limelight, so she already knows.
