Remember the mammoths, say the clean-cut organizers at the youth camp's mass wedding. "They became extinct because they did not have enough sex. That must not happen to Russia".
Obediently, couples move to a special section of dormitory tents arranged in a heart-shape and called the Love Oasis, where they can start procreating for the motherland.
This organization - known as "Nashi", meaning "Ours" - is youth movement run by Vladimir Putin's Kremlin that has become a central part of Russian political life.
Nashi's annual camp, 200 miles outside Moscow, is attended by 10,000 uniformed youngsters and involves two weeks of lectures and physical fitness. Attendance is monitored via compulsory electronic badges and anyone who misses three events is expelled. So are drinkers; alcohol is banned. But sex is encouraged, and condoms are nowhere on sale.
Twenty-five couples marry at the start of the camp's first week and ten more at the start of the second. These mass weddings, the ultimate expression of devotion to the motherland, are legal and conducted by a civil official.
Other pro-Kremlin youth groups are hounding homosexuals and non-White invaders off the streets of Moscow. Mestnye [The Locals] recently distributed leaflets urging Muscovites to boycott non-Russian cab drivers.
These showed a young blonde Russian refusing a ride from a swarthy, beetle-browed taxi driver, under the slogan: "We're not going the same way."
Such unofficial xenophobia matches the official stance. On April 1, a decree explicitly backed by Putin banned foreigners from trading in Russia's retail markets. By some estimates, 12m people are working illegally in Russia.
