Most people in the UK know little about the middle east, but they can recognise genocide when they see it. And being against Zionism is not anti-Semitic.
Hamas literally call for the extermination of Jews, and they start a war against Israel by butchering, raping and abducting 1200 innocent Jewish civilians.
When they lose that war (that they started), it's a genocide?
