Classifying something as simple as a still life painting as political seems like a stretch. Next up they will be firing people who eat fruit for breakfast.
I do think there has been a real increase antisemitic views fueled by politics and the media. It really sucks to be Jewish as all Jewish people are now tied to murders. Last time I checked Jewish people don't have control over the current Israelis administration. Even being Israelis doesn't mean you support Israel's actions in Gaza.
People need to put the blame on the leadership of Israel not random people who happen to be Jewish. I think a lot of the Pro Palestine movements are at least partially neonazi movements.
