My original comment was that the founding fathers gave us open borders. This guy responded that apparently the British attacking in the 1770s caused them to not have open borders? Then I tried to give him a few supporting facts and he just goes off the deep end. Slavery being made illegal is an immigration limitation? It would just mean that anyone brought to this country as a slave is no longer enslaved.

I’ve now posted these facts hundreds of times over many years and this is as good as any other argument against them as I’ve found.
