Actually , if you care about Western Civilization, we better start eating spinach --the demographic winter is no myth. At current birthrates in two generations there will be no more more Italians. Will the Muslim immigrants, who the elites are counting on to meet the demands of industry and the welfare state, carry on the values and cultures which have come to identify Western civilization over the last two millennia?
And just recently it was announced that birthrates in the U.S. are the lowest since recording began --just barely above replacement rate (and we have fertile Hispanic immigrants to thank for that).
