The Israeli state is a fascist ethnostate. Intelligent, rational people don’t equate disdain for Israel as antisemitism. Most people aren’t really that intelligent or rational though.
Discussion
Most states are terrible to their people, at varying scales. Israel is definitely up there though.
I would argue that the rational people shouldn't characterise criticism of certain facts surrounding the holocaust as outright antisemitism. It is similarly disingenuous to call it denial, because that is a propagandised term (~ 'safe and effective' or 'danger to democracy' or 'conspiracy theorist') because it presupposes that so called revisionists deny that any Jews were killed at that time, which is obviously ridiculous.
The issue I see coming down the road is that, because of how emotional the topic makes people, there isn't much room for a nuanced discussion, usually is just ad homs, there is going to be more radicalisation.
The State of Israel is a personification of Talmudic culture and religion (even among secular Jews who are highly influenced by the culture).
That culture and religion is what is evil - not Jewish blood, not Jewish soil. The evil comes from Jewish norms, Jewish language, and Jewish ideas.
