What I feel like people like Norman Finkelstein fail to realize is that to be against "Zionism" you are in fact against a piece of historic fact that has happened in the past. Unless you are to go back in time when Zionism was an ideal and not a piece of history, your thoughts on peace in the region would be relevant.
If you fight against Israel you are fighting against the Jewish people and you are ok with Jews not existing in this world.
