It's laughable watching the idiots in that video showing their pride with their Mexican flags and soccer jerseys despite the fact that they or their ancestors made a conscious decision to move to the United States. The simple fact is that millions of them and their compatriots would rather live illegally in the United States than remain in their homeland.
They would rather work for so called greedy and unscrupulous Caucasians for slave wages, without legal recourse, the right to vote or participate in democracy and live every day with the fear of deportation.
The simple, inescapable fact is that they have a better life living under an American government than they do living under a Mexican one. Yet somehow its the gringos that are the bad guys.
