He might be an asshole, but I'm not surprised to see reactions like these to the immigrant crisis. I see them more and more often around me as well (I am from Europe). And it might get a lot worse, already we're seeing arson and threats of violence against refugee centers.
The reason is simple: the fears and objections of Europe's citizens have been completely ignored. If a refugee center opens up in your neighborhood, you will experience an increase in crime and nuisance. The people in a village with 500 inhabitants fear the influence that a nearby center for 6000 refugees will have on their community. And a sizable portion aren't refugees or even from Syria; they left their own save homes to find a better life, and look for countries with generous welfare packages. In the Netherlands, the refugees already have had a serious impact on housing. Municipalities are obliged to give priority to people with an asylum status, which means they jump to the front of the queue for social housing. The waiting time for a regular family without priority is now 7-8 years I believe, with some larger cities having a waiting list of 14 years.
Some of the fears are unfounded and the objections unreasonable, and the harsh reality may be that we will have no choice but to put these migrants up somehow, somewhere. But the problem is that in the political climate it is impossible to even begin that discussion To ask what the cost of this immigration is, what the impact is, to question the motives of some of the immigrants, to demand that we finally get some sensible and well organized way of dealing with the immigrants instead of pancking at the last minute and putting them up in tents, or to demand that along with a generous welcome for the true refugees comes a program to actively screen and evict people who have no business here and to deter them from coming in the first place. Those questions get you branded as an unfeeling nazi, a racist, or worse. This discussion is carefully avoided by politicians and the media alike. Instead, we hear only the good news: these immigrants bring important skills, they bring wealth instead of costs, they will not alter our society for the worse, they are not terrorists, and they will generate jobs for us too. Meanwhile the actual problems are unacknowledged and thus not addressed.
An increasing number of people are starting to feel the pressure from increased immigration firsthand, and they are completely abandonded by their representatives. Immigration in the face of an emergency doesn't have to be a problem for the locals: when the government organize things well, are open and honest about what is going to happen, do what they can to alleviate any nuisances, and take complaints seriously, then you see the locals putting up with any troubles that remain. If however you ignore valid complaints, and brand any naysayer as sub-human white trash, then desperate people will lash out. In increasingly violent ways. And they will lash out against the refugees as well, which is the last thing they need.
That is my main worry. Not the immigration itself, but the unbelievable way that my government and Europe are handling this, or rather: not handling it.
