That unfortunately IS the Globalist agenda.....not that they have to assimilate but 'we' have to accept these communities (illegals and otherwise) , their cultures and lifestyles living 'alongside' of ours...which is 'Integration' of 3rd world countries into western nations whether they like it or not. That I do not agree with.
Fifteen or so years ago, there were guesstimates of one of every 8 people in the US being an illegal. That number is bound to be worse today.
