You are more likely than incest to pass on genetic defect if you already have a genetic defect like spinal biffita, downs, cleft pallet…by your standards, they should be regulated before incest, right? What about the mother whose had a hysterectomy and son whose had a vasectomy? It must be OK for father and son because it would be homosexual, right???? You can’t answer any of the questions because you’re a HYPOCRITE!!!
