TikTok says it’s not the algorithm, teens are just pro-Palestine — The company denied allegations that it has been promoting pro-Palestine content in an effort to sway American opinion

Jews were in high positions in the Arab world and iirc lived well. Much of the blame for the rise in anti-semitism is almost purely down to Zionism. Jews came to be seen as colonial collaboraters with the great powers against that region. In Algeria they literally were - the French were able to create a two-tier colonial society by giving Jewish Algerians who were native to Algeria citizenship and denying Muslims the same by claiming cultural incompatibility. Hence, Jews became a colonial force in that country.

In Iraq, Zionists terrorised the Arab (Iraqi!) Jewish community there by bombing Synagogues and cultural centers and collaborated with Iraqi nationalists to force Iraqi Jews into leaving for Israel.

So there are different experiences here, but almost all is down to colonialism and zionism.
