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).
> there are 1 billion Muslims to 16 million Jews
The vasty majority of Muslims are not in the US, the area relevant to the article. Also, to complicate things, afaik most Jewish Americans oppose Israel's right wing, especially the current government, and are sympathetic to Palestinians. And afaik most Israeli support in the US is right-wing evangelical Christians (if I am defining the subgroup accurately), a much larger group than Jewish Americans.
