Mexico is not coming here. It's citizens are. They know they don't have a right to be here, which is why they hide in their barrios instead of assimilating in the greater American culture.
They're hardly hiding. They are marching in the streets. And Mexico's government is pushing their people here as evidenced by the comic book showing them how to come here illegally, public statements, their attempt to fight the fence through international law and meeting with our politicians. It's our country, not yours! Mexico will not allow anyone to come illegally through their southern border, has armed troops to prevent this, yet think they have a free pass to the US. It's funny, how can you say they are hiding? Marching by the hundreds of thousands in our very streets is hiding? You sound like a politician trying to convince people Mexico taking over is a good thing or a member of La Raza (a very racist organization).
