@cicerone imposter,
The question was on whether how they got here makes any difference in terms of "assimilation". Many people are in the country because of illegal immigration (either because they crossed the border, or because their parents or grandparents did). By the second or third generation, it never makes any difference.
There are certainly millions of Americans who have at least one grandparent who immigrated illegally from Ireland, Italy, Poland, Greece or any number of countries. Yet now they are as American as you are-- in fact you probably would never know they are products of illegal immigration -- thanks to assimilation.
Ironically the same assimilation argument Advocate is using against today's unwanted ethnic groups were used against Irish, Italian and Jewish immigrants.
