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).
They could very well be more than that but you can't shut them all up. So that 36 to 1 might be after the fact.
Just from the populations you mention, which is obviously a super rough calculation, if we assume all Muslims to be pro Palestine and all Jews to be pro Israel, we would be expecting something like 60 to 1 ratio.
So the existence of that 36 to 1 might even be the result of the bias.
I am not saying this is the case, I'm just saying don't dismiss the claim simply based on the ratio you see.
