"Borders? We still have borders somewhere?"
Sadly, we have erased our borders and are allowing even criminals and enemies to move into our land in number and colonize and terrorize us. And they tend to have a higher birthrate than us. We're apparently heading into the 'interesting times' of the old Chinese curse. But on the other hand, optimistically, we can ally with the good majority of newcomers and get them to work with us against the bad of whatever ancestry. That would include waking up our own brain-dead liberals to today's dangers, and starting to enforce our borders and immigration laws once more.
