Why is there disproportionate hatred of Israel and Jews?

Why do so many people march on the streets when Israel is involved in a war to defend its own citizens? Where are all the people marching to decry atrocities in Syria, Chechnya, Afghanistan, or to Uyghur muslims in China? What is it about Israel, the only Jewish state in the world, and the only democracy in the Middle East, which causes people to be moved to protest in rage? Why is Israel held to a different standard to any other country in the world when trying to defend its own people from heinous acts of terror on its civilian population? And what positives can Jewish people take away from the hatred of them?
