Inclusion is overrated especially at the expense of assimilation.

Inclusion requires force or coercion.

Inclusion causes tribal strife and balkanization

edit: to answer your question, it's a euphemism for rejecting the Western canon and yes it is totally about control

Look at England: the political class wants to replace white English with Arabia and Africa. The rationale is they think it's easier to control a non white population with welfare bribery. Of course the political class is being naive if they think immigrants from certain parts of the world can be easily controlled.
