Having pride in the achievements or traditions of one's culture, nation, or ethnicity is natural and even beneficial up to a certain extent. After all, many people perceive their culture, nation, or ethnicity as an extension of their family, and we all take pride in the achievements of our family members. However, when pride swells to the point that we take our achievements too seriously, and we start to feel intellectually, ethically, and/or artistically superior to other cultures, nations, or ethnicities, then our tribalistic attitude can evolve into belligerence, oppression, hatred, and even genocide.
In short, cultural, national, or ethnic pride is healthy so long as it doesn't supplant our feelings of connection and responsibility to humanity as a whole. Humanism, which embraces all human life and holds humanity responsible for its own welfare and progress, is the only philosophy which cannot be perverted to intolerant extremism the way that less inclusive philosophies, such as religious fundamentalism or aggressive nationalism, can.
Regardless of which people we each perceive to be the best, our ultimate loyalty should be to the human race as a whole.
