What is the purpose of expelling black immigrants in France? What is the proportion of blacks in the French population?

France is expelling illegal immigrants, mainly blacks and Arabs. They didn't try to expel black immigrants. It is impossible for immigrants with residence to be expelled, and the law protects them. Only undocumented illegal immigrants will be deported. The proportion of blacks in the French population is not high, but the proportion of Arabs is getting higher and higher, which has exceeded 10%. This is a problem left over from the colonial era.
