Concentration camps and migrants

So the Hungarian government has decided to set up guarded camps for asylum seekers until their application is processed, housing them in containers. This, obviously, set off a hysterical outburst from a lot of western newspapers, and the comment section of the NYT's facebook page filled up with Americans drawing parallels to cattle wagons and containers, and also brought up extermination camps.

Well, putting aside the lack of historical knowledge, and the fact that these containers are the very same ones workers use as temporary housing at building sites (and nobody complains about exterminating them, or keeping them in inhumane conditions), and the fact that the present clusterfuck in the Middle East is principally the US' fault (Americans don't like to clean up their own mess, but are quite judgemental of people who are left with it), let's look at this issue, shall we?

First issue. A large portion of these migrants are not war refugees; this has been established over and over and over. Bangladesh, Morocco, Pakistan, and Tunis (among others) are NOT war-torn countries.

Second issue (which ties in with the whole "closing the borders" thing): Hungary is on the Schengen border. (Well, Greece is too, but nobody expects them to be able to close it.) Hence it is duty bound to protect the border. Even Merkel is talking about protecting the borders, and stopping the influx of undesirable elements, even though she also screamed murder when this protection actually was taking place. Just to recap: the borders are not closed. Anyone can go through the border control points, and apply for asylum. The illegal border crossing was stopped by erecting a fence. You come in, you apply for asylum, you wait. Whereas the 1.5 million people ending up in Germany came through the fields, and did not stop until Germany to apply for asylum. Which is not according to the rules. In fact, it's highly illegal.

Third issue: terrorism and other shenanigans. The Germans lost about 130 000 people. They don't know where they are. They can't be reached after they submitted their paperwork. A lot of rejected asylum seekers -no surprise- also disappeared. A sexual predator or two, a couple of terrorists also have known to disappear until they surfaced with their dicks in some poor kid, or behind the wheels of a high-jacked truck. So, with the knowledge that there is free movement within the Schengen zone I really, really would like to ask anyone who's complaining how they envision trying to keep the undesirables under control. Ahmed the terrorist can come in, claim asylum, and then disappear if you don't keep him in one place. During the process you might find out that he was sucking some ISIS boss' dick, or cutting heads off in his free time, it's too late; he is already in Germany or wherever, planning to do what terrorists do.

So I would genuinely be curious how you guys expect to screen hundreds of thousands of people and how you think you can deport them in case their application is rejected, if they are free to bum around the whole of EU.
