If Helen Thomas is Lebanese(and therefore an Arab) how is that a slur? If someone calls me a Caucasian or European, they are not "slurring" me, they are describing me.
Reminds me of a quote from the "13th Warrior".
Ahmed Ibn Fahdlan: My name is Ahmed Ibn Fahdlan Ibn Al Abbas Ibn Rashid Ibn Hamad.Herger: Eben?
Ahmed Ibn Fahdlan: No, listen, My name is Ahmed Ibn Fahdlan. "Ibn" means "son of".
Herger: Eben.
