This mod changes the European cultures; changes the primary and accepted cultures for European countries; changes "citizenship" issue; adds antiracist (and racist) decisions, which add or remove accepted cultures. The aim of the mod is to make migration and assimilation more realistic (for example, former Spanish colonies don't share the same or mutually accepted cultures with Spain, so they will be equally attractive for Spain and China; now they have mutually accepted cultures with former metropolises, which makes migration between them easier), changes relationships between countries (for example, Spain AI will be more interested in it's former colonies policy) and create a possibility for some cultures to be accepted (for example, Afro Caribbean has no country, where it is the primary or an accepted culture; now it may be added as such with the decision).
Afro European cultures may be accepted (and rejected as well) as accepted cultures in the country with the same White European culture as primary by the decision, if the rulling party surropts it. The same goes for white French (in Haiti) and Jewish.
