In 1967, after the Six-Day War (5–10 June 1967), Shahak ended his membership to the League Against Religious Coercion, because they were "fake liberals" who used the principles of Liberalism to combat coercive religious influence in Israeli society — but did not apply such protections to the Israeli Palestinians living in the IDF-occupied West Bank and in the Gaza Strip. In the event, Shahak joined the Israeli League for Human and Civil Rights, and became its president in 1970. The League, composed of Jewish and Arab citizens of Israel, protested and publicized Israel's restrictive policies against Palestinians and provided legal aid to them. Some settlers in the West Bank city of Hebron so hated him that in 1971 they had their pick-up truck painted with "Dr. Shahak To The Gallows".
