U.S. immigration as a right of return

With 1 million demonstrating in L.A. against making felons of illegal immigrants, and 300,000 in Chicago, and with the senate now taking up the issue, it is worth considering that Latino(a) presence in the U.S. can be viewed as a “right of return”, given that nearly 90% of Mexicans are of Amerindian descent. Americans have no business excluding the original inhabitants of the country from the country.

(From the wikipedia: “Mexico is racially and ethnically diverse. According to the CIA World Factbook, about 60% of the population is mestizo (mixed Amerindian and European), and another 30% is Amerindian or predominantly Amerindian.”)
