I am not certain, but if he was, she is deserving of criticism right along with anyone else who participated in such activity.
My point with Dr. Laura is this. None of us is perfect. If the fact that any of us has sinned disqualifies us from taking moral stands, then morals will have no advocates on the planet.
Where Dr. Laura's comments are within reason, they should be listened to and agreed with on merit.
Where extenuating circumstances exist, such as Laura not specificly posing for a porn concern, or perhaps not knowing a man is married, this should be taken into considertation. On the other hand, standards do cut both ways. If she did pose for a porn concern or did know the guy was married, she should have known better, and it is certainly fair to mention it.
