Several of these jump out at me immediately as being incorrect:
Chimps and bonobos certainly have comparable bone structures to humans and other primates, modern and archaic, certainly have similar skull anatomies.
The skin point I disagree with as there is such thing as melanin.
The adipose tissue point is out too, as sedentary primates such as those in captivity tend to have similar levels of body fat to humans, and very active humans tend to have similar levels of body fat to other primates.
Chromosome fusion is not a point I'd be willing to bring up if I was debating the classification of humans, as fusion of human Chromosome 2 is entirely consistent with the common ancestry of humans and other apes and one of the better arguments for common descent.
Lack of a baculum has at least three hypothesis, but there have also been several cases of humans being born with one, only to have it removed later. When you compare phylogeny and bacular size data on great apes, its clear that the close you get to humans, the smaller the baculum becomes.
Primates we are. Primates we will remain. The phylogeny shows it, the nested hierarchy shows it, the fossil evidence shows it and the genetic evidence shows it.
