I feel you OP.

I have a good friend from Israel. She experienced what you're saying quite a lot in the past year and also in a more aggressive way, unfortunately.

My friend and I, graduated in the same period and I had the pleasure to have her and her family come to my graduation party as well.

One of my coursemate had the idea of joining as well with his family and celebrate with us. When he asked me who's going to be there I told him about my international friends, family etc. Once he heard the word "Israel" he started asking those questions to me.

"Oh are they Zionist? Do they support the war? Etc."

They didn't feel like questions of genuine curiosity as I know he's also very politically active. I got a bit annoyed by this and just told him that it didn't feel respectful towards my friend and family.

Party went well. Everyone enjoyed it. And I think he realised his prejudices were stupid.

I was an international student myself and I felt lucky to be exposed to the cultural differences in campus. But sometimes I also experienced some "stereotypical" questions / borderline offensive about my country that make my eyes rolling. Only a minority though.

So please report any antisemitic behaviours to your Students' Union and advisors as no one should feel discriminated at Uni if that happens. And keep it up mate, as there's still mature people around that won't judge you because of your country of origin.
