Eugenics though radically racist had the right idea. Why not get rid of the mentally and physically defective of all races? The Earth is already overpopulated, so why not get rid of those who will do nothing except take up space. 7 billion would go down to 4 billion within 10 years! Let's forget right to life and admit humanity needs QUALITY not quantity.
With the de institutionalization movement of the past few decades persons incompatible with life have become a burden on society. Couple this with the Pro-life movement that condemns contraceptives and termination. The result is overpopulation with a lack of resources and healthy individuals. At some point society must choose to sink altogether or start cutting some fingers off to save the whole hand.
Please let me say that you want to get ride of the Mentally retarded to make room for overpopulated Earth. God made all of his children different in unquie, do we really want to euthanise (kill) someone on how they were born? If God made everybody different in there own ways what will he think about this. People with mental Retardnation can't speak so they won't have anyway to back out of there death but have to face it, is that what we as humanity are coming to? The retarded don't take up space, they live each day discovering new ideas and opening there brains with new knowladge. Why don't we get ride of the whites, or the blacks or mabye the Asians that is kinda what you are saying but with someone with a disabilty HECK YES THIS IS RACIST.
I concede your argument about God, but must remind you that most of the world considers religion obsolete and those who still believe as enemies depending on where one lives. As the world moves towards a Godless society humanity has to take matters into its own hands in order survive even if those hands have to lose some fingers. Since we are already a (supposedly) post racial society it is time to begin looking exclusively at the weak of all varieties to weed out in order to facilitate a huge leap forward for the rest of humanity. Sounds cold and ruthless, but religion tells me that only God knows how to create a utopia of plenty and bliss, so until this fabled genius returns humanity has to get along as it can.
You want to euthinanise the ones who were born mentally retarded and can't control that they were born that way or did anything, but what if we euthinanised off all the criminals that accually did something or took someones life away. Doing this will probaby lower crime rate, the population and natural resourses that we need to live of of... Think about that
