If anything the skew within the platforms is to prioritize pro-palestinian views https://twitter.com/committeeonccp/status/173279243496103143...
It also seems like these platforms create (rather than support) anti-Israeli views: https://twitter.com/antgoldbloom/status/1730255552738201854
US views skew pro-israel, and GenZ is closer to 50/50, so if there's something going on online, it's not in favor of Israel.
It's probably relevant that there are 1 billion Muslims to 16 million Jews, and that the largest relevant population of pro-Israeli internationals is India and Indian Hindus, and they are not on TikTok (blocked in India).
But conflating anti-Israeli views with anti-Semitic views does a disservice to Jews and Palestinians alike.
Anti Israeli government: It's not antisemitic.
Anti Israeli people: It's antisemitic.
Criticizing Israeli settlements in the West Bank is not antisemitic. But suggesting that Israel has no right to exist as a Jewish state is antisemitic as it implies ethnic cleansing.
Both are arguably criticisms of the Israeli government.
You've got it backwards. The only way for Israel to exist as an ethnostate is through an ethnic cleansing. That's not specific to Israel; that's inherent to the concept of an ethnostate.
The assumption that Israel can only exist as an ethnostate is itself a political assertion - it's the hallmark of right-wing Zionism.
I had a discussion at length on this with some very historically learned people (far more than me) shortly after the attack, with the context of Biden's response.
The underlying cultural memory is that of the Holocaust, and of thousands of years of oppression and pogroms before, where nobody would ever help the Jewish people if they were in danger. Thus the belief that the second the Jewish people became a political minority in Israel, they would be immediately and inevitably subject to ethnic cleansing and persecution by the government. Jewish supremacy is viewed as the only way for Jews to be safe in a world full of people who either hate them or don't care enough to help.
This explains Biden's "bear hug" diplomatic approach as well, which as much as it was directed to Netanyahu, was actually directed at the Israeli population (and he is now much more popular than Netanyahu is, from approval polling). The only way to defuse the situation long-term is to convince the Jewish people that if they accept peaceful co-existence without enforced ethnic supremacy and apartheid; and the only way to do that is to convince them that if they are threatened, that they will not be left to die alone as they feel they have been so many times before.
You're describing the reason that some Jews say they support the creation of an ethnostate. That's still an ethnostate, and treating Israel as synonymous with a Jewish ethnostate is the defining right-wing characteristic of Zionism.
It's important to note that what you're describing is not representative of the general opinion of Jews, either globally or in Israel. Many Jewish Holocaust survivors and their descendants oppose the creation of an ethnostate through ethnic cleansing.
