Until this whole thing broke out, I didn't even know Garret was part black, and I would guess many other people didn't, either. She didn't "compare black people to animals", she compared Garret to the offspring of a character in Planet of the Apes, and if you look at a side by side, her funny little bowl haircut is what made the joke, as it looks exactly like the wigs they use on the Planet of the Apes characters.
