There is a supporting history. Over the last millennium, Jewish people’s presence has aggravated their host country or they’ve been scapegoated many times. Resulting in a need for their swift exodus.

It is very recent that the West was favorable to Jewish people at all, on a country by country basis. With the most inroads occurring after some sects of Christianity latched on to the recreation of Israel as being part of their own prophecy.

So there is an understanding that even this is thin acceptance and symbiotic where both groups are pawns to the other without much care for understanding each other.

But there are people that question the government policies of Israel without questioning its right to be a government at all.

I can see why it’s ambiguous to distinguish, and the best defense is to invalidate opinion. Its just disingenuous when the stated opinions they are invalidating are the same opinions they and others hold within Israel and some Jewish communities: The military campaign is unpopular. The coalition government has no coherent way to meet its goals. Every choice the IDF makes isn’t “Hamas’ fault”.
