I might be old-fashioned. But I always thought that most people who have children are optimistic about the future. They are confident in the world their children will be growing up, and growing old, in.
I'm that way. I have four children, and believe that the greatest place and time in the history of the world to be alive, is right here, and right now. So many of the liberal and enviro persuasion feel the exact opposite, that between rising seas and falling oil supplies and polluted air and water and CO2 that it's a crime against humanity to have children. Child rearing is the ultimate sign of civilizational confidence, and the Europeans have none. The past two generations of moral relativism and squeamishness, of seeing no difference between Kruschev's Russia and Nixon's America, and of having the Yanks pick up their defense tab--have dulled their senses. They're perfectly content with their unaffordable pensions and their month-long state-mandated vacations, and don't mind importing millions of immigrants to make up the difference. So, now, entire towns are depopulating, and countries are emptying out. Eastern Europe is halving its population every 40 years.
Last one out, please shut off the lights. Not that it matters much. The Muslims will wind up with Europe, after all. Funny really, that after centuries of warfare, they will take it by default. Jesus said, "The meek shall inherit the earth". Not sure if he was thinking of post-Christian Europe at the time, and I'm fairly certain the Muslims don't read the Sermon on the Mount anyhow. But in the end, it'll work out for them--all they had to do was wait, patiently.
