hmmm yeah i can definitely see how this can be called racism
but still, we can't really call it racism unless we know exactly what Parker was thinking when he wrote this - it seems obvious that there is some prejudice here, but you never know what goes on in another person's head
if every Arabic character he draws starts looking like those guys, and if he uses a pretty obvious stereotype in his comics, then you can safely call this racist
until then, we can only really speculate
afterall, I'm pretty sure that there are indeed fat, lustful, and rich Arabian men in this world with buck-toothed bodyguards there are also black, white, and asian guys like that too
