Dumbest pro-illegal immigration comment

On the radio earlier, I heard what has to be the dumbest comment yet by the folks in favor of illegal immigration. A Latino guy was being interviewed and he said "Look at this country's origins. When the pilgrims got here did the Indians ask to see their visa? No." Okay, and tell me again how did that work out for the Indians? Heck, his argument actually bolsters my position of there being a need for greater border enforcement.
