The publication Law and Gender from an Intersectionality and Diversity Perspective aims to promote feminist, gender-based intersectional and diversity approach in knowledge production within legal theory, studies, and practice. A crucial feminist intervention in legal theory and practice is necessary, because law is traditionally shaped—behind allegedly universal and neutral norms—by what is called male-streamed creation, interpretation and implementation. The mentioned feminist intervention is crucial also because struggling against gender-based discrimination and for achieving substantive gender equality is a systemic and urgent educational, political and civilizational task. Discrimination based on gender has always intersected with other forms of discrimination, because “the women” is a generalized notion that represents very diverse individual women in terms of class, race, colonial history, age, (dis)ability, educational background, ethnic, religious and cultural origin, political and economic system background, historical heritage, urbanization status, migratory status, and more. The rationale of this book is in the idea that legal theory, practice, and education should be based on competencies and a willingness to comprehend and prioritize the intersecting discrimination faced by minorities and vulnerable groups, with particular attention to women and girls, as well as LGBTQ persons, who often face oppression. Law should recognize and mainstream more visibly, directly, systematically, and consistently the position of those who are subordinated, demeaned, deprivileged, and marginalized. The intention of the book is to apply the intersectional feminist approach to manifold legal and close to them non-legal items, related to different fields of legal studies and legal practice.
