The ridiculous thing is that even the UN talks about replacement:

Kerry Bolton:

The Rightist claim that Europeans are being replaced in their own homelands by alien migrants and refugees is lambasted as a ‘lie’, and in the words of the ever-dubious Wikipedia as a ‘nationalist right wing conspiracy theory’. [...]

Yet from at least 2001 the United Nations started referring to ‘Replacement Migration’. The theory laid the foundation for the U.N. Migration Compact. The U.N. document Replacement Migration, Is It a Solution to Declining and Ageing Populations statistically examines the demographic trends of ‘developed’ states, USA, Europe, E.U., Russia, Japan, and Korea.

Economic globalization is the real push for open borders, and a primary means of destroying the barriers to international capital, not only economically, but socially, culturally and ethnically. This explains why the international oligarchs hatched this Compact, under the guise of what is now called “social investment.”

While the U.N. refers to the integrity of the states, this is more double-speak as is also refers to states as being fluid and without fixity of heritage or destiny, “making us all countries of origin, transit and destination.” This means a globalized mass humanity without roots, able to be relocated across the world as marketing needs require; the perfect scenario for what G. Pascal Zachary lauded as “the global me.”

The U.N. Global Migration Compact is an initiative of global capital. The aim is the free flow of labour, as part of the free flow of resources and capital to benefit an international oligarchy. As is usually the case, it is done behind a humanitarian façade. [Cont...]

Replacement, or white shift as sociologists like to call it, is only a conspiracy if we mention it.
