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.
