While it is understandable that the Danish government would wish to expel an individual for publicly stating his pleasure so insensitively at a terrible massacre, it is true that this comes amidst various unfair measures across Europe aimed at combatting extremism. In France, Switzerland, Germany, Poland and the United Kingdom various measures have focussed on the minutiae of Islamic culture, targeted the innocent as well as the guilty and have stoked the flames of Islamophobia, and by extension, that of Islamic radicalism.
It is also important to remember that the Charlie Hebdo attracts were about Islamic extremists attacking the newspaper that was critical of Islam (and racist in their critism) and that Denmark has been wary of outsiders, especially muslims, but expelling someone over a Facebook post is definately going too far.
There is no could be about this, he should be deported. He is living in a safe. clean country and he brought his filthy ideals with him, just like the rest of them. He needs to be sent back to wherever he came from, war or no bloody war!

I do not believe countries have gone too far in trying to combat extremists; rather, I think they are simply implementing new tactics and utilizing new sources in order to uncover information and intelligence. With the current technology and facets of social engagement available to us, there is a much greater pool of information to gather and sift through, and new ways to uncover potentially threatening activity among citizens.
