Zionism shouldn’t be necessary if you observe mitzvas. Supplementing Hashem’s Torah with an -ism implies that the Torah’s philosophy is lacking in some way and needs supplementation.
That being said, the Zionists who go pitch their tent in dangerous areas in Israel may be misguided, but they are our brothers and sisters and we are obligated to love them and help protect them from the Arabs who want to spill all Jewish blood.
The bloodthirsty, savage, fascist, Islamic terrorists who go by the moniker “Palestinians” are the enemies of every Jew, and trying to appease them by throwing Zionist Jews into their claws and fangs will get us nowhere. Jewish sects who blindly teach their children to hate Zionists (and I’ve seen it too) are even more misguided than the Zionists.
