R. Kelly vs Michael Jackson

Everyone is up in arms over Michael Jackson, and rightly so.  But what about singer R. Kelly?  I have seen on the news that he has been accused of having sex with an underage girl and video taping it.  Now he is saying that the "incident" happened during a time period that the girl could have been between ages 13 to 17 years old.  If she was 17 at the time then it would have been legal in the state that it happened in.  Has this hurt his career?  Does anyone care?  Is it because he was with a girl and not a boy (like Michael was accused of) that no one seems to care?  People quite buying Michael's records, but that doesn't seem to happening with R. Kelly.  Interesting fact:  R. Kelly wrote a song that is on Michael Jackson's latest CD.  He also wrote the "outrageous" one that Brintey Spears is singing.
