First of all, Obama's parents were not of the same "race", so the pic is implying that his "white" mom was a chimp, too; not just his "black" dad. And then Obama himself is a "racial" mixture and is also portrayed as a chimp. That seems pretty even-handed to me. Offense handed out all around. If being a chimp is somehow insulting, that is. Plus, I still see lots of pics of Bush as a chimp. No one claimed that was "racist". In fact, I think both instances would be insulting to chimps if they were aware of them.
Chimps are not a race of human, so how does comparing a person to a chimp qualify as "racist"? Would it be racist to show Obama as a snake or a bunny or a toadstool or a rock?
Finally, do chimps have "race"? If they do, humans (other than maybe Jane Goodall) can't tell by looking. Which means it must be pretty superficial. Could chimps discern that humans have "race"?
I think Obama is a very, very corrupt and bad person. As has been every other president I have ever learned much about. Being a chimp would be a vast improvement.
