That's the point. Uk 'has involvement' with all sorts of countries & issues. Only Israel gets the huge demos, demands of universities, politicians & everyone else to state their position. What other geopolitical crises have led to museums, art galleries & theatres feeling compelled to issue statements?
Criticism of Israel IS antisemitic when Israel is singled out and held to different standards - such as the huge number of UN resolutuons condeming Israel at the UN - more than all other countries combined in 2022.
The General Assembly approved 15 anti-Israel resolutions in 2022 compared to 13 resolutions against others.
6 against Russia & 1 against North Korea, Afghanistan, Myanmar, Syria, Iran, US.
Saudi Arabia, China, Lebanon, Turkey, Venezuela and Qatar, were not condemned by any resolutions despite all actively involved in human rights abuses &/or regional conflict.
Haven't got the figure for 2023 to hand but its part of a longstanding pattern.
Sometimes you need to call a spade a spade.
