Yes we are.
Diversity should favor good traits specifically, yet we humans have trumped natural selection and are tolerating bad traits as well.
In the past, it was survival of the fittest, and though that sounds harsh, it is actually good.
Thanks (not) to the newest "equality" propaganda, we have allowed unfit people to survive as well as fit, and you wonder why the earth is overpopulated with poor people.
The newest anti-"discrimination" movement is for things like Down's syndrome, low-function Autism, physical deformities, not being able to walk, type-1 diabetes, etc. It costs the world too much to keep these people alive, and since it is now a "good" thing, people with these diseases are having children and passing the diseases on.
Humans are the ONLY species in the world that tolerates differences. Every other one stigmatizes the different. It is not natural and bad for society to tolerate differences to this degree.
