"Zionists" means different things to different people. Let's assume she means Americans who place the interests of the government of Israel above the interests of the people of the United States. That still isn't technically a crime. It isn't treason. It is a thoughtcrime. I hate the government of Israel, but I hate domestic tyranny far more.
Zionism is essentially Jewish Nationalism:
Jewish nationalism for some. Jewish expansionism to others. Nationalism should always be a concerning impulse.
Nationalism in the sense of supporting the existance of a Jewish state. Zionism has a specific definition. Of course that doesnt mean that people dont use it incorrectly.
I'm an anarchist. I oppose all states, because they are territorial monopolies in violence operating under usurped authority. The government of Israel demonstrates this no less than any other.
Thanks. That would have been easy for to look up but I like it better when it is explained to me. :)
