"Celebrity Interracially Adopting-For Love Or Publicity Boosts?"

Celebrities are transracially adopting children on what appears to be a regular basis these days. Brad Pitt and Angelina Jolie, Tom Cruise and Nicole Kidman, Sandra Bullock, Madonna and Charlize Theron are probably the most notable. With the pros and cons of different cultures being raised into foreign cultures already already up for debate, and the recent public expose of Madonna spewing a racial epithet at her adopted son, is this an indication that celebrities are adopting transracially for publicity boosts? Or are they truly trying to give unfortunate children a shot at a better life?
