Why are Afghanis and Pakistanis in Greece? How did they get there? Who let them in? Why until now have they been allowed to stay? What is the likelihood that they will integrate into the society of Greece, and come to think of Greece as the place whose history they can share, whose instiutitons they can accept, whose culture and language and literature will mean so much to them? 

And the same question, slightly rephrased -- for "Afghanis and Pakistanis" read "Muslims from anywhere" and for "Greece" read "France" or "Great Britain" or "Italy" or any country in Western Europe or North America, or f any Infidel land, with its non-Muslim history, and non-Muslim institutions, legal and political, and its non-Muslim social arrangements and understandings -- should be asked.

How is it possible to believe, knowing what we now know about Islam, and its texts, and its tenets, and the natural attitudes that Muslims display, and the atmospherics of societies, communities, families suffused with Islam, how is it possible to think that Believers, ready to promote Islam or, even if they are not quite so fervent in their faith ready to misrepresent it to Infidels (and thus to prolong Infidel unwariness and confusion) out of filial piety, embarrassment, and a residual loyalty that cannot be shaken even by experiencing the freedoms of the West -- how is it possible not to recognize that the admission of large numbers of Muslims  into non-Muslim lands endangers the political and legal institutions, and the safety of the people, in those lands.

How is it possible to continue to endure the lax and even criminally negligent immigration policies, and the failure by the authorities, by the political and media elites, to recognize the truth -- that so many people have come to recognize -- of the following statement: 

The large-scale presence of Muslims in non-Muslim lands has led to a situation that is far more unpleasant, expensive, and physically dangerous, both for the indigenous Infidels, and for other, but non-Muslim immigrants, than would be the case without that large-scale Muslim presence.

Try to tell yourself you don't believe in the truth of that remark. Try.
