Cultures ascend and descend over time. Germany was an underdeveloped backwater in the Roman days, but a world leader now. Britain ruled the world for centuries, but is not anymore nearly as influential. China was undoubtedly the most advanced civilization in the world a few millennia ago, but nobody would have called it that in the 20th century. There are still tribes in the world who remain unconnected to modern society and die young of treatable illnesses.
Unless you believe in moral relativism, it's absolutely possible for some cultures to be backwards compared to others, at different points in time.
Female genital mutilation is prevalent only in the Islamic world[0]. Do you not consider that backward? Is it racist to condemn this practice?

In fact, at least part of the current culture enjoys destroying (or looting) historical sites from those generative cultures.
The culture you are calling "backward", created math, the modern camera, algebra and so many things crucial to the modern world.
I dont see you calling Germans backwards even though they were in a similar shape less than a 100 years ago.
This isn't an issue with the culture because these issues won't be left so ignored in their countries.
Ask other immigrants or ones still living in the warzone, they will be absolutely surprised how these criminals aren't locked up and absolutely destroyed.
