Which migrants to get rid off ? from Africa first ...then will be Slavs and Jews.Like old times .....
It is extremely silly, Iwonka, to see the problem of immigration in the light you see it.
First, it is your anti-German sentiment that makes you say you are glad that ISIS members from Africa in Germany make Germany weaker. Every country, Germany included, has the right to defend itself against extremists and dangerous elements like ISIS people by not letting them on their territory.
Second, the number of immigrants that suddenly goes up and eventually exceeds a certain level, starts to become embarrassing (to say the least) for the host country, causing serious social and economic problems there. The level of immigrant people in the population which used to be thought of as safe in Western Europe long before the recent immigration crisis began was typically set at 5% in France, the UK, the Netherlands and elsewhere. But not only the level itself is what matters most, perhaps the pace at which the number of immigrants is rising is even more important.
And third - as Weimarer pointed out to you - it is unfair to reproach people from Germany for calling to get rid of immigrants, while at the same time Poland has been firmly saying "no" to any attempts by the European Commission to impose 'quotas' of immigrants on us.
