Well, considering the manner in which South America was colonized, her argument falls flat on its face. The Texans were not without their share of legitimate grievances at the time. But, typical leftist, she has selective memory when it comes to reading history. In fact, many of these grievances were enshrined in the Declaration of Independence (Texas' version).
And, being the simpleton liberal that she is, she has to boil it down to something easy - like racism. It can't be the facts:
Illegals don't pay their fair share of taxes.
Illegals don't bother to teach their kids English in a large number of cases, resulting in the dumbing down of schools.
Illegals don't pay for health care. Don't believe me? Show up at a TX emergency room and see the number of hispanics there with non-emergency issues.
Many hispanic illegals come from a culture that does not value the law, and they think that this culture should work for them here in the US. (culture =/= race).
And on top of that, the US has a MUCH more humane treatment of illegals than Mexicans themselves do when they catch someone coming over their southern border, which means that Mexico's stance on immigration is hypocritical at best.
It has nothing to do with skin color, and everything to do with two cultures that do not mix well under the set of rules we established in our own country.
