The way that girl has been acting as of late.. with the partying, the getting high and even with her own admission on Saturday Night Live, she is a big girl now. I know that doesn't seem to make it right.. but, she isn't little "Miss Disney" anymore... and even THAT doesn't make it right...
There really isn't going to be any REAL defense of making a sex doll of ANYONE'S likeness any better, unless that person is already in the porn industry. But, she and her father did make themselves open to the public once fame set in. Hell I remember seeing one time a Janet Reno sex doll.. now if THAT isn't hitting an all time low :P
