America is ushering in a new culture. This is very uncomfortable and stressful for many, some even violently resist, but resistance is futile. The change that is now in it's infancy will blossom rapidly and all must come to understand that the day of the WASP, even though it's existence is more fantasy than reality, is at its end.
In the past there were many migrations to America, some done freely and other by force. Look at the chart below taken from: http://www.prb.org/Publications/Articles/2014/us-migration-trends.aspx
It should be clear from the above that for the past 100+ years that most of the immigrants to the US were from Europe. Yes, different languages and traditions, but all sharing various aspects of a common history. While their were definite clashes, the melding pot notion ultimately worked.
"In 2014, Mexican immigrants accounted for approximately 28 percent of the 42.4 million foreign born in the United States, making them by far the largest immigrant group in the country. India, closely trailed by China (including Hong Kong but not Taiwan), and the Philippines were the next largest countries of origin, accounting for about 5 percent each. El Salvador, Vietnam, Cuba, and Korea (3 percent each), as well as the Dominican Republic and Guatemala (2 percent each), rounded out the top ten. Together, immigrants from these ten countries represented close to 60 percent of the U.S. immigrant population in 2014."

Things are changing and totally different cultures (India, Middle east, etc.) are taking root in America. This is not cause for concern or fear. In fact, it should be celebrated and embraced . As we know from biology, the greater the biodiversity, the healthier and more vibrant the environment.
A generation or two down the road, assuming we're all still here, there will be confusion as to what the fuss was all about.
