You say that wee are going against nature by allowing the weak/stupid to live....

Love keeps these people alive... somewhere deep deep down there... its love keeping these stupid/weak people alive.

My cousin has A.D.D., and personality disorders... but he makes us all laugh and wee love him for who he is, and wee take care of him whatever he needs.

Wee are not going to abandon him because he is slow... wee are going to help him live on because wee love him, he is family, and he deserves life as much as you or I.

So if you consider 'love' to be a part of nature at all, then your argument is flawed.
