Please someone help me translate this sentence in English, so that it sounds like a protest.

No hegemonism - it's our own world.

Explanation: Concise and powerful speaking does not require clauses.

Hegemonism, I encountered it in SAT reading, specifically refers to politics hegemony.

In addition, it is more authentic to use NO to express boycott. For example, before the independence of the North American colonies, the slogan against British taxation of the colonies was No taxation without representation (resist taxation without parliamentary representation!)

If "all mankind" must be highlighted, it can be ：No hegemonism - it's a world of all humans.

I feel that directly translating belong to belongs to is rather stiff.

Another: There is a grammatical error in the sentence of the first classmate - please help to correct it by the way,

Resist supremacy, for the world belongs to mankind.

Mankind already belongs to all mankind and does not need to be adopted by all.
