Secession is not practical.
According to who? The globalist cartel that dominates America? The Lunatic Left or the Retarded Right? Secession may be a political oddity now but I can promise you in the decades to come it will become a serious concern. Have no doubt in that regard because America's incompetence and its love of diversity will make it so. Want to bet on what the political landscape will look like in fifty years or so after whites have reached minority status?
