"You're a racist and an anti-semite" Today people throw out these terms way too loosely, imho. And technically aren't the palestinians semites?
Since the question was regarding what constituted Semetic, I went back to the origin of Abraham.
The particular passage "wild ass of a man" refers to Ishmael, the father of all Arabs.
He will be a wild ass of a man;
his hand will be against everyone
and everyone's hand against him,
and he will live in hostility
toward all his brothers."
Genesis 16:12
