Some feminists are really very interesting people. Science cannot unambiguously clarify which one — nature or nurture— fundamentally determines personality traits and human behavior, but some feminist movements already distinguish sex (biological factors) from gender (social factors), insisting that social cultivation can significantly modify social roles and behavior patterns and radically change the perception of traditional masculinity and femininity in the social system. In fact, without reliable scientific verification of the relationship between nature and nurture in the predestination of future human life, they offer a firm ready-made belief in changing this life with education and upbringing. And this is one of the essential differences between science and political ideology, which also includes feminism among others.
