Migrants coming to Europe will spurn norms of European society

Of course there should be a humanitarian response to the migrant crisis but there needs to be more long term thought about the consequences of those naïve fools who call for the gates of Europe to be opened. 

I bet none of the armchair liberals will themselves have to live with the consequences of such a step or have to compete against migrants for scarce resources. As usual it will be migrants who are placed in already deprived areas and left to fend for themselves in isolation against disadvantaged locals.

Who are these migrants anyway — where are they coming from; what is it they are seeking?
