NOT hurting anyone? WTF?!! They are hurting their children psychologically and Im not even talking about conceived from both but the once they already have! These children when they go to School and later have Jobs or are in any social environment they will be made fun of, maybe frowned upon and these may cause them to have a stressful, depressed childhood, adulthood! and they are NOT hurting anyone?!! Not that I care about what they do with their lives but to say you are NOT hurting anyone is flat out WRONG!!
