The idea that all humans have exactly the same mental capacity, physical capacity, proclivity for crime, etc., is so fucking dumb I can't believe anyone buys it.

The further idea that there is no noticeable race-correlated trend with respect to the above is even fucking dumber. Like, do you not know about horse breeds or dog breeds?

Lastly, the idea that any human being should have any fewer rights owing to his reduced capacity is abhorrent. It's also not being put forth anywhere on this site, of course.
