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.
The modern israeli's are not semites. Those that settled after WW2 were eastern european converts, khazars, with no genetic ties to the middle east. Those that are not ashkenazi are migrants from the surrounding countries, who largely did not move to the area until after the occupation of palestine.
The term "anti-semite" was invented to reinforce the lie that the ruling class of israel have some ancestral claim to the land. Using it is playing into that propaganda.
