You think he would condone the calling of Jews satanic? He was a Jew himself.
I wouldn't get so legalistic as to even try to answer that question, kind of like 'how many angels do you think can fit on the head of a pin?' It is very common in the christian world for people to make such accusations even against each other. How many christians have you heard say that the catholic church in Rome is of the devil? Listen to any christian talk show and you will hear christians saying that the teachings of some other christians are false or from the devil or satanic. So, I wouldn't worry about such statements from one man.
It bothers me more that some people, like you, question the christian faith of these people because they are arabs or because they're oriented towards being opposed to israel in this struggle. You called them 'christians' as if they're not really christians.
