May I politely ask here, why the flag is such an issue for you?
Waving the flag of any country doesn’t mean you support a government nor its military policy. Plenty of people wave British flags at numerous occasions, it doesn’t mean they’re a fan of Rishi Sunak or they’re in favour of past British military excursions.
By the same degree as you have mentioned, should many British Jews feel appalled by the Palestinian flag? Since it is often waved by antisemites AND peaceful protestors?
i would argue most people wave the israeli flag in solidarity with family and friends, not for political reasons. People are human beings, no matter who their government are.
You’re making this into something it is not and dehumanising israelis at the same time, since many of them oppose netanyahu, want to live in peace, and are also being tarnished by the brush of the government, to be labelled ‘white supremacists’ ‘Nazis’ and everything else they are all being lumped in with. I don’t see anything wrong with supporting other human beings.
