Au contraire, the term 'anti-semitic' has been hijacked by a vocal minority and fellow-travellers. My Oxford (admittedly a trifle dated) says: 'Semite--member of any of the races supposed to be descended from Shem, including especially the Hebrews, Arameans, Phoenicians(are they still around?), Arabs and Assyrians.
From dictionary.com
Sem·ite ( P ) Pronunciation Key (smt)

and
semite

So if we go along with your view of the meaning of 'antisemitism', what do you call someone (an Israeli?) rubbishing a Palestinian---a patriot?
