That was a serious question in the context of the posted article.
The Danish government has continued to monitor people in Denmark, in recent years. They, often randomly, call people (Danish born and heritage) mostly those born outside Denmark yet to Danish parents to ask if they feel ‘integrated’.
That isn’t a bad thing as such.
But, those muslims or Islamists (whatever you call them) were Not born outside France or Beligum (Paris or Brussels — nor San Bernardino). They were born and raised inside France, Belgium and USA — sadly.
Point is, once you don’t and Can not differentiate, you’ll end up with a massive prejudice as did Nazi Germany with the Jews. Round them up.
Since the article specifically talked about a Danish citizen helping non-Danish refugees, I am not sure where you came up with the differentiation comment.
And someone who is trying to enter or travel through a country illegal should be highlighted. If they are doing the traveling illegally, there might be a nefarious point to what they are doing.
If you are discussing different Danish citizens being highlighted, than your point would be spot on, but the article was not about that.
