Poland's lawmakers have approved a European convention against domestic violence following a stormy parliamentary debate, in which many said the convention threatens traditional family structures.

The lawmakers voted 254-175 with eight abstentions on Friday to empower President Bronislaw Komorowski to sign into law the 2011 Council of Europe's convention on combating violence against women and domestic violence. It obliges governments and organizations to penalize such violence and help victims.

Many right-wing and Catholic lawmakers said some of the regulations undermined Poland's traditional roles of mother and father in the family. Some said its article about education would promote confused notions about gender. The article says that children should be taught about "non-stereotype roles" in the society and culture, which critics interpret as challenging the traditional roles of men and women.
