From my vantage point, I see nothing the mexican illegals have done to promote this. I do see hollywood crap, inner city ghetto crap, and liberal caucasian politicians contribute to the creeping destruction, but the contributions by the mexicans have been minimal.
I am not laying the current social atmosphere solely at the feet of illegals, but they are one piece of the puzzle. The fact that they feel entitled to enter the country in violation of our immigration laws combined with the authorities lax enforcement of those laws is part of the creeping effect I referred to. The worst part is that everyone has become so feminized that no one dares to call the illegal activity what it is for fear that they will be labeled racist and xenophobic. And that attitude doesn't just hold for illegal immigration, but most of those things we, as a country, used to hold as wrong for the good of society. We are told there is no right or wrong any more, no black or white, only shades of gray. The boundaries of society are eroding and once the boundaries are gone, anarchy will reign.
Yes they only make it more and more likely that some kind of integration between the two nations will happen. It will be an open border relationship and not a political merger if we are lucky. Then again youd probably be just fine with that. There arent many ghetto blacks or liberal whites in mexico, just mexicans, so why is mexico so corrupt and crime ridden right down to the lowest office and law enforcement officer?
