Ok fine, I did five minutes of research.
Article from Aljazeera which supports your argument: https://www.aljazeera.com/opinions/2023/12/13/its-not-shocking-to-see-israeli-children-celebrate-the-gaza-genocide
Fun fact: Aljazeera is based in Qatar, which supports Hamas, so it's probably not an objective paper. https://www.cnn.com/2023/12/11/middleeast/qatar-hamas-funds-israel-backing-intl
Article from "The Jewish Voice and Opinion" which gives completely the opposite view, that palestinian children are taught that jews are subhuman. https://www.cnn.com/2023/12/11/middleeast/qatar-hamas-funds-israel-backing-intl
Again, probably not an objective source.
And here we have an article from Time: https://time.com/6323178/antisemitism-israel-gaza-attack-essay/
