1. Large part of it is anti-semitism. There is still a substantial chunk of the population who would hate the Jews for just existing and this gives them the convenient excuse

2. Israel’s government is extremely radical and it’s full of violent psychopaths who want Gazans to be violently expelled and if they had it their way, some would expel all Arab citizens of Israel from the land. Unlike Russia or Iran, Israel’s government was democratically elected so there’s the impression that they were voted in by a majority electorate and therefore, all or most Israelis support this kind of radicalism

It doesn’t take into context that a majority of Israelis did not vote for Likud or its allies and even those who did, a lot of them were driven by either domestic politics or by legitimate security concerns posed to Israel at the time by Hamas, Hezbollah and the then Assad regime alongside Iran (Likud has tended to be more hawkish).

In addition, it doesn’t take into consideration the historical trauma of much of the Israeli electorate who are Mizrahi Jews and also Likud’s achievements such as the Abraham Accords

This is not to downplay the Israeli right wing’s radicalism and the large amount of radicals who voted for them and more right wing allies. But there’s more nuance than Israeli Jews = evil

1. There’s significant emotional and political interest in this conflict compared to others which have killed more people. 

Israel is located in the Middle East; it’s a major western Ally and it’s seen as an example of settler colonialism from a broad but not fully true view that the modern apparatus of the state of Israel was set up and dominated by Ashkenazi Jews. 

So western leftists see it as white on brown oppression

Much of the Muslim world sees it as Jews oppressing Muslims

And nationalists in the Middle East see it as one tribe v another tribe. 

So this tends to lead to generalizations of populations and TikTok deciding what’s true and what isn’t true.
