It is a huuuuuge problem in Europe and Europeans are not happy at all because people feel threatened and I do understand them.
Let's ask first who and why people's countries and homes are destroyed that they have no other choice than to leave their countries?
In some schools here in Vienna we got 80% foreigners and only 20% Austrians. Imagine the problems in daily live trying to mix many cultures and religions. It could be utopia to live together in peace but I am "not a dreamer" ....
Imagine !
