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.
That is the #1 tactic used to build smearing campaigns against people critic of Israel. The difference between being a racist and expressing disgust for what Israel has done in decades to the people of Gaza and the West Bank is so huge that either people using the word "antisemite" in that context are deeply ignorant, or they simply have an agenda. To my knowledge, most journalists and/or politicians aren't that ignorant.
* Bibi's racist amalek "genocide the palestinians" trope.
* Ben gvir when he hangs a portrait of Israeli terrorist Baruch Goldstein up on his wall.
* Isaac Herzog when he calls race mixing a tragedy.
(To give an example of 3 people who obviously represent Israel, all of whom are proudly racist).
