This type of message has been making the rounds at pro-amnesty demonstrations.
William Bradford, Priscilla Mullins, and John Alden as undocumented aliens? Yup. They've even been rehabilitated as noble illegals by shameless liberal hucksters (who typically prefer to ignore or denigrate the Pilgrims' contributions to the historical record).
Here's the Rev. Hurmon Hamilton, earlier this year: "When William Bradford and the Mayflower pilgrims arrived at Plymouth Rock in 1620, they did not bring any immigration papers. When John Winthrop arrived in 1630 with the next wave of New Englanders … they were not met with a wall built to keep them out. Just as undocumented immigrants from Europe in the person of John Winthrop and William Bradford and undocumented immigrants from Africa … helped to build the old America in the then-New World, undocumented immigrants today are needed to build a new America in this new global world, and we need to say yes to that.”
