This open challenge to the Christians or should I say to all non-Muslims by the either convert or Suni Muslims is a threat which should not be taken lightly by any civilized government.  These Muslims are misusing the tents of their respective Constitutions towards liberty of speech and freedom to practice their religion literally.  They have found the weak link of western nations which is to respect the dignity of each individual, treat all human beings with respect and grant them equal rights under their Constitutions.  That is the reason they are outspoken in the European and American cities.  It may be true that under the Constitutions of civilized western nations, respective governments are not allowed to take any legal action unless these fundamentalists get involved in a terrorist activities which might entail death of individuals or destruction of properties.  But the leaders of the western nations have to bear in mind that if these brain washed people are allowed to speak anti-national slogans and threaten openly to the rest of the people, the time will come that they will over power the mind of lot of innocent people  by converting them to Islam.  We have so many cases in front of us right now where lot of westerners have joined the ISIS forces and they will not hesitate to slaughter the non-Sunis on a heart beat.  Therefore, the sources of proliferation of this fanatical ideology needs to be stopped and eradicated.  Simple way of eradicating this problem is to change the Constitutions to the effect that anybody making any anti-national statements will be treated as a traitor and punished accordingly.  Secondly, deport all illegal Muslims to their respect countries.  European and American leaders ought to take a cue from the Australians on this issue.  Australian leaders told to all Muslims either they should abide by their local laws if they want to live in Australia or they have a choice to get out of that country.   If Australia can do it why cann't European and American leaders follow suit.  If your Constitution consists of some old time clauses about this issue which may not be pertinent now with the change of time, it needs to be changed.  Constitution remains a piece of paper if it allows these radical elements to grow and become conducive for the Christians to lose their country.  If you lose your country to these fanatics, what good is that Constitution?  IT IS AN OPPORTUNE TIME FOR THE EUROPEAN AND AMERICAN LEADERS TO WAKE UP AND ERADICATE THE PROLIFERATION OF THIS RADICALISM, EVEN IF IT REQUIRES AN ANNIHILATION OF ALL THE PROPONENTS OF THIS IDEOLOGY.
