We humans as well as gorillas, orangutans, and chimpanzees are all great apes (with bonobos sometimes included in among chimpanzees and sometimes broken out as a separate specie).
We humans differ among ourselves in skin color as well as in hair color. Furthermore, we have mostly lost our hair. We are sometimes referred to as hairless apes.
The other apes have hair all over their body. Furthermore, they are all pink-skinned and the various species have hair colors that generally range from brown to black, except that male gorillas have grey hair and orangutans have orange hair.
Considering hair color, Trump has sometimes been depicted as an orangutan. This depiction is considered to be good fun, not racist.
It’s like clownish comedians. If white like Charlie Chaplin or Red Skelton, it’s good fun. But, if black like Stepin Fetchit, it’s racist.
I think the rule is this: black people must always be portrayed as serious, intelligent, honest, law-abiding, etc., etc., and never in a demeaning or belittling way. But, white people can be portrayed in almost any way imaginable.
Thus, “Scotch tape” doesn’t demean Scotch people. The “Fighting Irish” doesn’t demean Irish people. And, the “Minnesota Vikings” doesn’t demean Scandinavian people. But, God forbid you have an Indian squaw on a package of butter, or a black woman on a package of pancake mix, or name a flavor of a soft drink “Chinese Cherry.”
I remember the Trump=Orange Orangutan thing. I didn’t remember it was Bill Maher, but I remembered someone doing it, and no one called it racist.
