In a colony ruled by a colonist group there is no democracy. Because people did not choose their representative, instead the government is imposed in the colony by acts of invasion or external contracts beteween other nations, as happened with Brazil when Portugual and Spain shared it in The Treaty of Tordesillas in 1494.
Colonization is a brutal process that kills culture, local history and causes many damages, so to say there is features that are mostly ready accepted in a governement is hard to. Now about resent most of it is related to the exploration of natural resources, the imposing of tax, the expropriation of lands from natives and the cultural impositions as religion, language or even system of education.
