They do it because it works. Conservatives are trying to split the country into Balkan states. What they don't realize is that they and the liberals, are being used by an establishment trying to destroy the concept of national independence.
Silly issues based in obvious lies and distortions are encouraged on both sides so that the one-world establishment (consisting of both liberals and conservatives) can divide and conquer.
If you don't believe what I'm saying, then consider the condition of our so-called union. America is bankrupt, no longer produces anything of real value, it's citizens are either unemployed or underemployed and in serious debt, while all they do is yell and scream at each other arguing about irrelevant issues. If our leadership and our own stupidity isn't responsible for our state of disintegration than who or what is?
And who is at the heart of the problem? The one industry that prospers when everything else is doing well or suffering, the worldwide banking establishment. Is it a conspiracy or is it just the way things are. I choose to believe it is the latter. But I also choose to believe that strong intelligent people can change it, but not by participating in our sham democracy.
The first step is to ignore the idiot birthers and start attacking the people who make certain that America and the world will never be debt free. We overpay for housing, transportation, and medical care and once we're finished paying our federal, state, local and hidden taxes we use our credit cards to pay for food, entertainment and expenses incurred by our children's education and presents for holidays, birthdays, etc.
This entire country, as well as most of of the world, is now controlled by banks. Debt has eliminated the need for them to stage major wars as a way to power, but this lack of war is no more benign than the predictions of George Orwell in his book 1984.
So please, let's put the silly bickering behind us and realize that we're committing suicide if we don't start fighting the people who are really to blame for our sickly condition, and I think that our health should be our number one priority, don't you?
