Greenfield opposes the Israeli occupation of Palestinian territories and supports a two-state solution to the Israeli–Palestinian conflict along the Green Line with "minor adjustments". She describes herself as a social democrat and a supporter of a strong welfare state. She does not follow any rabbis, claiming that contemporary Israeli rabbis do not advance the interests of their followers. She also accused them of not preparing their followers for the Gazan disengagement plan. She remains Orthodox, rather than choosing Reform Judaism or Conservative Judaism, because she believes in continuity, feels close to Jewish tradition and history, and is committed to observing Halacha.
