Personally, I couldn't give a stuff about cultural diversity.
Come on, people fight against change in their lifestyles all the time. You don't care because nobody is challenging yours.
Some people in California died trying to protect their homes from wildfires. Instead of evacuating, they stood in the face of towering flames. They didn't want to move their homes, they didn't want to lose their belongings, their way of life. Is it really so hard to understand?
Different people and cultures choose to put value on different aspects of their lives. You happen to put it on human suffering and individual rights. Other people see it differently.
