Yeah, I heard that dog whistle. And I have heard it in my own family: when visiting my mother during the beginnings of the travel ban, she turned away from Fox and told me it was A Good Thing that Syrian refugees were being turned away because "those people are animals, they're not human."
Never mind that I married someone who is half Syrian and her beloved grandson is a quarter Syrian. I guess their skin is light enough to pass for human? I mean, wow.
