First of all, you need to chill on your anti-latino shit. Those who come to this nation are hardly the invaders you propose they are. Most come here looking for more money and wealth than they have in there native lands. That is a very American concept.
People went all out against Italians when they moved here, claiming that many were illegal and that others were breeding crime. Have they assimilated? Yes, and America has adapted to there presence and our culture today has many Italian elements. It happens with all groups of immigrants. That is why we have so many different styles of food, music, etc.
America is not a white protestant steak eating nation that allows others to live as guests. We are a culture of people from different backgrounds always adapting and adjusting to an influx of new cultures and ideas.
No matter how much you hate the idea of latinos building homes in your precious white America, it will happen. The current American culture will continually blend with the incoming cultures of the newcomers. You will be absolutely powerless to stop it...so you might as well buy a pack of corona order a burrito, and enjoy.
