Good points.
Every year 2.5 million (mostly old, white, majority R voting) people die and are replaced by (mostly minority, heavily D voting) folks.
It definitely makes things an uphill climb.
Think about it. When the USA’s largest demographic group of white/Christian/heterosexuals (who possess a long-held, cherished set of beliefs in morality, staunch work ethic, property rights, rule of law, limited government, national sovreignty, secure borders, etc.) is slowly edged out by a coalition of demographic groups with a different makeup and a different set of moral codes (in some cases radically so), you have the recipe for a seismic shift in the foundations of societal, governmental and economic systems, not just a mere replacement elected officials. The same electorate that made a president out of BHO (2X) is the same society that will tolerate (and advocate for) further injury to the former majority group out of a sense of righteous indignation in order to achieve ‘social justice’. In reality it is just the same old motivations that have plagued mankind throughout history: greed, revenge, lust, and racial hatred.
But the same success and benefits that the current coalition of demographic ‘in-groups’ now enjoy will be short-lived. The problems inherent within these groups will, with a certainty, be their demise as well. Homosexuals cannot biologically reproduce. Socialists inevitably feed on their own, destroying any hope of having a productive tax base. Historically, anti-Christianism ultimately works against itself and, over time, will actually ADD to the numbers of Christianity.
And the Earth shall continue to turn and the cycle shall begin anew. It just might take a hundred years (+ or -).
