I don't know all the books in question.
The greta Thunberg is nitpicking. Does the big balloon trump make us all Anti American?
And the Muslim and Christian charities that help homeless people are, I suspect, the Muslim sisters of Eire and some other Christian charity . I think the Muslim sisters of Eire are the only non Christian or secular charity operating in homelessness. There is no Jewish homeless charity in Ireland. Charities here tend to be secular or have Christian roots.
I don't think kids are taught anti semitism in school but Ireland is very pro Palestinian - it is not controversial here, it is the default position. On my road there are at least 4 Palestinian flags in windows. A kid in the street could tell you about children suffering in Gaza. The focus is on horror at the suffering, a hope for peace and a two state solution being the answer - not antisemitism or anti Israel.
