No, a person's usefulness in a family is not determined by their gender. The idea that one gender is more useful or valuable than the other is a harmful and outdated belief based on gender stereotypes and discrimination. In a healthy and functional family, the roles and contributions of each individual should be based on their abilities, interests, and personal strengths, rather than on their gender.
Both men and women have unique qualities, talents, and skills that they can bring to a family. Gender should not be the sole determinant of someone's worth or role within a family or society. Instead, families thrive when there is mutual respect, support, and cooperation among all members, regardless of gender.
In modern societies, there is an increasing recognition of gender equality, and many efforts are being made to challenge traditional gender roles and expectations. Embracing the diversity and individuality of each family member, regardless of gender, is crucial for fostering healthy and harmonious relationships within families and promoting a more inclusive and fair society.
