Immigration has always been a euphemism for invasion. No native white population has ever approved of or benefited from mass immigration. It is always bad, and it is always forced upon you by your rulers.

The only time mass immigration is beneficial to the local population is when quality people migrate to a shithole country. This is “colonialism”, and it is now universally condemned. So immigration, in practice, is a one-way pipeline of shitty people into prosperous white nations, and the results are consistently terrible for those white nations.
