zeuhl, you have to admit with the advent of easy mobility, trains, planes and automobiles, people move with ease across the world, settling in places they wouldn't or couldn't have done once upon a time, financially constrained or indeed because of border constraints, now that has virtually gone, almost anyone can settle any place they choose, and many have come from the sub continent and Africa, to settle into many countries in Europe, including UK, and they have had an impact on the populations already established. If many are adherents to Islam, it's not without some concern that the spread of Islam is far more widespread, that we have seen with a number of home grown fanatics that their way is the only way. Moderate peoples can be led into following others with a more serious and sinister agenda, haven't we seen this all before.
