anyone who criticises Israeli government policy is an antisemite   

no one here has done that but:

Making mendacious, dehumanizing, demonizing, or stereotypical allegations about Jews as such or the power of Jews as collective - such as, especially but not exclusively - the myth about a world Jewish conspiracy, or of Jews controlling the media, economy, government or other societal institutions.    CHECK

Applying double standards by requiring of it behaviour not expected or demanded of any other democratic nation    CHECK

Drawing comparisons of contemporary Israeli policy to that of the Nazis.    CHECK

Let it be clear: Criticism of Israel is not antisemitic, and saying so is wrong. But singling Israel out for selective condemnation and opprobrium - let alone denying its right to exist or seeking its destruction - is discriminatory and hateful, and not saying so is dishonest.      CHECK
