I have nothing but contempt for Jews who put their heads in the sand and ignore the danger of leftists who are in bed with the islamists. As for Hollywood types--they identify as liberals, not as Jews. If and when they do identify as Jews, it's only to make some ridiculous liberal point, not because they feel any kinship to the original recipients of God's word. : )
I must admit that I am baffled by those who claim to be Jews on racial rather than religious grounds.
