Culture is destiny

This quote is the most important. Don't quibble over stuff like what flag we're going to fly, or language we will speak. Or what is the exact form of government Britain now employs. These things all take second place to the issue of American culture. What is it now? What will it be in the future?
The culture the first Americans came from wasn't perfect. It involved slavery, and oppression of women. But, within it was a respect for private property, and a right to choose any religion or none. Within it was the concept that one's home is his castle. The tenth amendment showed the idea our founders had that people in different regions might want to do things differently, and that this should be respected.
Those things that the largely Anglo-Saxon, heavily Britainized culture were born with led to the condemnation and destruction of slavery and respect for those same rights for women, and the once enslaved blacks.
Nowadays, those same concepts are being threatened by two things.
#1. Modern American Liberalism, which looks upon property as a community granted privilege, regions with less people as not as important as regions with more people, and religion as okay, as long as it isn't too radical or strange. It also has within it those who would like to see the whole one's home is his castle thing done away with as anything more as a privilege.
#2. Foreign cultures which have no inherent concept of a BOR, or inalienable rights. Look, cultures which don't respect people's rights are inherently inferior to cultures that do. Current Mexican culture (from everything I've seen), only respects power, and machismo.
hint:
As long as we continue to allow Mexicans to flow across the border, those who have had it with that culture will escape here instead of changing their country, and their culture.
