I believe it's to domesticate humanity. If you look at the laws you'll see the way they (the government) want us to act, which is constantly changing through ineffective legislation over a nation too large and growing to fast to be controlled by a selected few candidates. Still, they think it's wise to continue war on the "nation's" people and other nations at the same time. If they wan't you to act a certain way, speak a certain way, and put all your faith in them and, preferably, Jesus Christ simultaneously, I think it's too much to ask for and the government want's the same out of millions of people. Getting rid of people they don't want or giving them a chance before law enforcement gets rid of them is clearly a form of domestication and could be considered genocide, just not as straightforward in some cases.
How do you feel about the government's true purpose, and, really, how effective is it (in your opinion, of course)?
