Maybe Britain didn't need to Brexit since the whole thing is rollicking toward collapse anyway. Here's the European problem, as succinctly summed up by Gatestone Institute:
In one generation, Europe will be unrecognizable.You can read more at their International Policy Council's website.
Eastern Europe now has "the largest population loss in modern history", while Germany overtook Japan by having the world's lowest birth rate.
Europe, as it is aging, no longer renews its generations, and instead welcomes massive numbers of migrants from the Middle East, Africa and Asia, who are going to replace the native Europeans, and who are bringing cultures with radically different values about sex, science, political power, culture, economy and the relation between God and man.
And good news, America's birth rate is plummeting now too so we can be just like Europe! Yay for us.
So let's keep warning about the dangers of overpopulation and scaring people into not having children. Because you're doomed to childlessness and financial ruin because you voted yourself the next generation's money and then declined to actually produce a next generation. Brilliant.
