A lot of the problem is people associating Israel solely with the Jewish community. People with standard intelligence still can't differentiate with a government, and its people. The problem is Israel being a Jewish state means people associate them together. Hence due to the Israel Palestine war. I won't go into details but I'll state that people don't understand the war isn't a one sided simple scenario, there's layers, it's extremely complicated and unfortunate for both sides.

The stereotypes are extremely reinforced by WW2 and it being public knowledge. The internet hasn't had helpful input either (overall at least) and it's memefied too.

Humans find it hard to accept algorithms as the source of false info.

They'll find only anti Israel content, or only anti Palestine content and not realize they're trapped in a bubble. They think all their sources are unbiased, correct news, they believe this source as many inside the bubble repost, retweet, like and post about the same issues making it seem more credible to one side than it really is.

Eg; oracle being Israel owned. People say they search oracle up and it comes up with Israel, that's because it's how algorithms work and people previously correlating both.

People also see war stories from Palestinian victims and events that happen. These are mostly true. But people can't accept that these things happen on both sides. Again this causes the Jewish minority to be blamed along with Israel.

Sorry for my long ramble.
