In some instances, encouraging multicuturalism is an appropiate measurement to adopt in some nations, in some others it is not.
Multiculturalism is expected to help develop national bonds as well as common goals.
However, multiculturalism is usually about inmigrants who strive to impose their ways upon their new neighbors. Division is created when any specific group refuses to integrate by not speaking the commonly accepted language or becoming part of the general culture, for example when inmigrants not only refuse to accept the same religion and holidays but they demand their own to be recognized.

Conflicts between these two factions have even escalated to violence in the last 30 years due to these reasons.
Some of the states were confederate, meaning they didn't want a lot of government involvement, so they were against having a constitution because they wanted to be able to run the states how they wanted to. Hope this helped!
