And rightly so. And the blame for that falls entirely on the shoulders of the zionists.
The zionists, by conflating opposition to Israeli government policy with antisemitism, have effectively asserted that being Jewish is indistinguishable from being a supporter of Israeli government policy. That’s the only way that opposition to Israeli policy can be considered antisemitic - if support for it and being Jewish are identical and thus interchangeable.
So all it takes for an individual to adopt a genuinely antisemitic viewpoint is to oppose Israeli government policy and to believe what the zionists are saying. They’re saying that being Jewish is indistinguishable from being a supporter of Israeli government policy, so if one is to effectively oppose Israeli government policy, then one must, by the zionists’ own logic, oppose Jews broadly.
And as an added bit of irony, what all that means too is that the zionists actually are antisemitic. By effectively assigning a specific, and in the eyes of many a repugnant and hateful, set of beliefs and behaviors to any and all Jews, entirely regardless of the actual beliefs and behavior of any individuals, they are engaging in the exact dynamic that defines bigotry, and thus antisemitism.
