Here's why:
* Social categories are groups of people who share common characteristics or attributes that are socially meaningful. These categories are often used to classify individuals and influence how they are perceived and treated by society.
* Race, nationality, and gender are all socially constructed categories. This means they are not inherent biological realities, but rather social constructs that have been created and reinforced over time.
* Social categories are not static and can change over time. For example, the concept of gender has evolved significantly in recent decades.
It's important to recognize that while these categories may seem natural, they are ultimately social constructs with significant power to shape individuals' experiences and opportunities.
