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).
The videos of destruction and death in Gaza are far more horrific than corresponding videos in Israel, because the scale of what Israel is doing to Gaza is so much greater than what Gaza has done to Israel.
Another way of saying it is, it makes sense that someone who spends hours on apps optimized for empathy-based addiction would be more sympathetic to Gazans than someone who reads the newspaper or watches talking heads on TV news, since the latter portray the occupation as a two-sided tit for tat.
Maybe you haven't seen enough of what happened in 10/7 then. I would rather get hit by a bomb then tortured to death in the most horrific way possible.
