An anti Semitic conspiracy theory is a false claim that claims that Jews are behind something that they’re really not, or it blames Jews for something they’re not responsible for. For example, conspiracy theorists and anti semites claim that Jews own all the banks in the world, but that is false. They also have claimed a few hundred years ago that the Jews kill Christian children and use their blood on matzah, but that is also false. All this is done because anti semites are looking for a scapegoat to blame all their problems on, or they just hate Jews
