While the CIA-led invasion of Syria has folks now worried about refugees, for the past two decades hostile refugees have been pouring in from Africa and Asia. Shortly after entering they may enter a green card program and become citizens in 5 years.
At that point, any relative of theirs has priority in immigration. Additional refugees are usually sent to cities that already have some prior immigrants from that country. This means that a mere 20 or so refugees can easily balloon into thousands over a few years.
Refugees are only one small part of the problem. In addition to the 70,000 - 100,000 refugees we get each year, we also allow in about half a million immigrants, plus TEN MILLION "non-immigrant visas" every year.
These H1B, etc visas add up so that more than 10% of the entire population of America is actually a foreign worker, not to mention the fact that they may over-stay (effectively immigrate) and are almost never deported. US visas are subject to "diversity visa" policies that unduly award non-Europeans immigration and foreign worker privileges; this is less of a problem now that the Indians, Chinese, etc have diploma mills and as students to American universities are virtually guaranteed graduation.
Compounding all of this, there are at least 15 million illegal immigrants in America, probably more like 30 million. And, among the legal and "native" citizens, millions are second generation immigrants thanks to "anchor baby" policies.
America is completely fucked. They say we're still over 60% non-hispanic white, but when you factor these things in and remove the West Asians, Jews, and Middle Easterners that they are counting as white, we are almost certainly ALREADY a majority-minority in our own country.
Thought you'd want to know Holla Forums. There is no getting the country back. We need to retreat, strengthen, and wait the plague out. Also, Montana is fucking awesome.
