“Men are from Mars, women are from Venus,” says therapist John Gray, who claims that men and women are two completely different beings, as if they came from different planets. Men are aggressive and warlike, but also protective like the Roman god of war Mars. Women, on the other hand, are emotional, beautiful, vain, and fertile like the goddess of love, Venus. This leads to the idea that men and women pursue two completely different reproductive strategies and that each of their traits – be they physical or intellectual – serve this reproductive strategy: men and women are biologically completely different and the differences in their behavior are for the most part biologically justifiable and determined. It can also be deduced that her sexual behavior has completely different goals and ideas (he only wants to distribute his sperm, she wants a romantic relationship and children). The social role, i.e. society, plays no decisive role; Everything, or at least almost everything, is biologically justifiable.
