Lots of countries have one or more official languages. What’s different is the purpose. Most sane countries define one to facilitate clear communication and transactions. China’s forcing this to extinguish a culture.
Also “deranged white thought” is a pretty racist take when the flag bearing “white guy” countries of the United States and the UK both do not have an official language while most of the rest of the world generally does.
It’s always fun to read people’s justifications for brutal occupation.
