If Zionism is racism, so is every nationalism.
Yup. Etienne Balibar: "Racism is not an 'expression' of nationalism, but a supplement of nationalism or more precisely a supplement internal to nationalism, always in excess of it, but always indispensable to its constitution and yet always still insufficient to achieve its project, just as nationalism is both indispensable and always insufficient to achieve the formation of the nation or the project of a 'nationalization' of society."
