Good points you make. The demographics have changed in America. But not in the world. Europeans have always been less percentage wise in the world. The 2 billion people who will be added by 2050 will not be mostly people with cultural ties to Europe. That is not necessarily bad or good; that just is. Africa and Asia will gain the most. Yet, my only point about the replacement theory in the U.S. is it is not some plan, some coordinated effort to "replace." The Immigration Act of 1965 was a game changer for America. It was passed amidst all of the civil rights agitation. It forever altered the country's demographics. But America (I guess at the time) wanted the law. America had no issue with diversity. There is no plan though. It happened because America created opportunity and people around the world said, yes, and so they came. India just so happened to adopt an educational focus on STEM studies amongst the population there. That started after independence. That's why they come here and keep coming. China loves our universities. So they also come. America is going to look like California soon whether Trump gets elected or not. The babies in the country right now are majority from other countries though they were born here. Ask for your exit question, "White people" are not being replaced really. No more than African ethnic groups were replaced when they got to the West and procreated with Europeans, or were raped by Europeans or the same with other African ethnic groups and Indigenous people. The various European ethnic groups who came here or were sent here are in no danger of dying off or going extinct. Culture, history, and tradition sustains people. I still ask myself - what is "White." What is "White" culture? It is nothing but a caste system. I would prefer "American" on those forms we fill out and then let the person write in whatever cultural or historical naming for themselves i.e. African American, Jewish American, etc. by choice but not mandatory.
