"なぜ白人になりたいと思わなければならないのか"

Simplified Meaning:

The quote is expressing the idea that a person doesn't need to change who they are to fit in or be accepted, specifically focusing on the issue of race. For example, imagine a person who loves their culture, their traditions, and their background. They might see no reason to change their identity to fit what society might consider as 'better' or 'more desirable,' like changing their skin color. In history, many people have been encouraged to adopt traits of the dominant culture to succeed or be welcomed. For example, during the early 20th century in America, many immigrants were pressured to speak only English and abandon their native languages to be accepted. But holding onto one's identity doesn't mean you can't succeed; it means you bring diversity and richness to society. Applying this to daily life, it encourages people to be proud of who they are, whether that’s their race, culture, or background. Embracing your true self and not feeling the need to conform to others' expectations can lead to greater self-respect and happiness. By showing confidence in your identity, you contribute to a world where diversity is valued.
