Immigration vs. Colonialization

I was reading this post from the Advice Goddess blog and realized something as I was adding my comment (I seem to be doing that a lot lately).  The discussion in question was in regards to burkhas and feminists and religious freedoms and such.  But the comments started talking about France and their ban on the burkha and I had a light go on.  France's reason for passing the ban on burkhas is because they are a symptom of immigrants not assimilating into French culture (along with not speaking the language of their new adopted land, etc.).  And I realized that these communities that refuse to even learn the rudiments and adopt just a few of the cultural norms of the place to which they emigrated are really colonies. 

In the West's zeal for fairness and multiculturalism, they (we) have allowed colonies, some of which are inimical to our way of life, to be set up under our noses.    According to wikipedia (yes I know, not the best source), colonialism is defined as follows:

Colonialism is the building and maintaining of colonies in one territory by people from another territory. Colonialism is a process whereby sovereignty over the colony is claimed by the metropole and social structure, government and economics within the territory of the colony are changed by the colonists. Colonialism is a certain set of unequal relationships, between metropole and colony and between colonists and the indigenous population.

In the case of France as well as the US, we have people coming in and setting up their own communities.  How this differs from immigration of the past, is that formerly, people would come and they would have their own neighborhoods, BUT they would learn the culture and would be able to interact with the larger community.  Now, they don't bother and they want the larger culture to change to accomodate them.

Just something to think about......
