Abstract
The fusion of immigration and multiculturalism problems generates new legal challenges and a constitutional quandary focused on the Equality as a fundamental right. Discriminatory practices by gender such as anthropological practices, cults and traditions have been imported obstructing any legal relativism in the framework of an alliance between different civilizations. The Equality as a constitutional principle and as a multiculturalism limit involves a constitutional answer in relation to discriminatory practices that emerges from religious freedom, forced marriages and other coercive behaviors suffered by immigrant women.
Keywords: Gender discrimination, Multiculturalism, Religious freedom, Violence against women.
