Bae will be fine in the UK and especially in Ireland because he’s not Jewish.

Jew hate is rather strong in Ireland. Support for Hamas is the highest in the western world. Israel closed their embassy in Ireland a few months ago due to unacceptable Dublin policies that are anti-Israel.

Edited to add: it’s not a walk in the park in London for people of obviously Jewish faith, I mean people who present on the street as a Jew. So, if you are Jewish you should probably stay in the United States and not flee to the UK or Ireland. But maybe avoid Columbia University?
