Not quite yet, but soon. The official propaganda had these "marchers" as wanting to join America, and believe it or not there seemed to be more American flags than any other. Maybe the LA march will by the very nature of the situation there be more militant, but Chicago's seemed like part of the usual minority victim pleading for justice racket then a call to arms.
When I hear, "!Aqui estamos, y no nos vamos!" shouted, I hear a battle cry.
I listen to Spanish talk radio a lot. Nobody is talking about fitting in, assimilating, or learning English. Quite the opposite. It's all about their power increasing, and the Latinization of their virtual states-within-states.
They could care less about becoming Americans, other than demanding all of the rights and benefits of American citizenship. It's about taking over. You have to listen to Spanish-language media to get this.
What I don't understand is people who leave Mexico to come here and then want to turn it into Mexico.
