....and social darwinism is a lot like freudian theory in how it's viewed. Some good ideas there but they need altering to really work. And if we were truely under the sole discresion of nature on who got to live and pass on their genes that are more suitable for the environment at the time...thus "superior" since that's the word thrown around in this one, then we wouldnt have people who pass on dominant genetic disorders. We are the only species that can manipulate our environment to the extent we do.

Talking about things being superior and natural selection does not transfer directly to people for these reasons. The mechanism of natural selection was proposed to understand how things work in responce to their environment and yes, to intraspecific competition too in regards to rescources. Homo sapien sapiens do not have the same relationship to their environment as other animals but it is going back a few hundred years in thinking to say that we are completely unaffected by such things simply because we are human.
