Genetic screening allows for parents to give their children the possibility of living a life without a debilitating genetic condition. Surely those who live with these conditions would not want to have other endure their pain, when there is an option not to.  By having these genes that cause such pain, and short life expectancy eventually removed from the gene pool we are also increasing the strength of the human race.  Genetic screening is only to be used to prevent and let families know about genetic defects. It is not discrimination to want humans to not bear genetic defects that debilitate their life, or end it premature through pain and suffering.
