Jewish feminism is a special kind of feminism where people who are both Jewish and feminists work together to make sure that women are treated the same as men in Jewish culture and religion. Just like how you don't want someone treating you unfairly because you are a girl, women who are Jewish don't want to be treated unfairly because they are Jewish too.
Jewish feminists work towards making sure that women can do things like read from the Torah (which is a holy book in Judaism), wear things like prayer shawls, and participate in all aspects of prayer and religious ceremonies. Sometimes, in Jewish culture, there are traditions or customs that are set up that treat women differently than men. Jewish feminists think this is not fair, and they want to make sure that women have the same opportunities as men.
Jewish feminists believe that everyone is equal, no matter how they identify themselves or what religion they practice. They work towards making sure that everyone has a voice and is included in Jewish culture and religion equally.
