This was evil and wrong but I do not believe that we have a genocide going on in this country. I respect your belief that we do but I see no proof of it.
We have been quietly killing off some elderly and disabled for a long time now, hidden away from the public view, by denying them nourishment and hydration. I believe, but don't have stats, that some cancer patients are deliberately overdosed with chemo and possibly morphine to speed along the death process. It is seen as more merciful, and indeed it may be, but it is still playing God.
The only case I cold endorse for pulling a feeding tube *might* be in some medical conditions where pumping liquid food into a cancerous stomach or hydration would cause more pain and discomfort in the terminally ill.
