Sounds like they are afraid of losing their own culture and want to bring down their "brainwashing" techniques to cleanse away what one brings from another culture rather than having a coalesce and diversity of understanding.

It's called epistemology and acculturation.

Either way, there is only one way it has always worked to make everyone be one culture... Well, may be a few ways. The first ways are war, oppression and genocide and those in tow do pretty good job of making one complete culture... Depends on what one is fighting--a religious culture, which is the history of the world or a vague spiritual culture where nothing is written down... It is very hard to erase a religious culture. It is rather easy to kill off parents and tell the kids what to believe in spiritually, if you allow the kids to live. Most governments don't last that long if they follow such a creed, it would be a crime against humanity and we now have the Hague and other "elements" to make that not occur, depending on what continent we are discussing. It won't ever occur in Europe, again... But it occurs all the time in Africa...

The second way makes people feel better about government-sanctioned "brainwashing" and that is everyone gets busy with everyone else... Then it doesn't matter what one's original culture was, it's what they feel best suits them--what they feel connected to... That "one size fits all" mentality...
