I read in magazine that there are rumors that Bobby Kristina (whitney houstons daughter) may be eloping to marry her adopted brother. I dont know if this is true or not, but it got me thinking how does society view this. Is this right or wrong? I ask because when I was younger I watched a movie "CLUELESS" with paul rudd and alicia silverstone and they were step brother and step sister and they fell in love and at the time I thought that was ok. what do you think
