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).
Looking at Germany for instance, anyone remotely criticising Israel for even gross violations of international human rights or Geneva Conventions (for instance for withholding water, food, medicines, and electricity for 2.2mil civilians in Gaza) will be attacked, silenced, stigmatised, smeared by the majority of media, politician, police, attorneys, etc. Many artists, intellectuals, activists, thinkers, academics have been cancelled, smeared (for instance Greta Thunberg, Ai Wei Wei, Candice Brice, Ilan Pappe, and many many more). And even more people are afraid to speak about Israel critically, fearing to lose their job or called antisemite, when in fact Zionism is not Judaism and the state of Israel does not represent all jews around the world, and cannot be sacrosanct.
In the US the support is even larger. Just today the US vetoed a Security Council decision for a ceasefire in Gaza. And this inspite of many people in the state department internally rebelling against this blind support for Israels retaliatory move in Gaza.
Disclosure: I have family in Israel, some of them went to the streets in Tel Aviv every week for months to protest against the judicial overhaul. And who are in panic mode seeing the right wing coalition partners of Netanyahu getting stronger and stronger. And I have family members in the military who after 7/10 want to „kill arabs now“. I just do not think flattening Gaza and/or dehumanising Palestinians will make Israel any safer.
