The Declaration of the Rights of Man and of the Citizen had been adopted during the French Revolution in 1789. It specifically affirmed freedom of speech as an inalienable right.
Article 11 provides for the freedom of expression as :
"The free communication of ideas and opinions is one of the most precious of the rights of man. Every citizen may, accordingly, speak, write, and print with freedom, but shall be responsible for such abuses of this freedom as shall be defined by law."
The Universal Declaration of Human Rights, under Article 19 adopted in 1948, stated that :
"Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers."
I am sure that the West are only using the freedom of speech as the means and ways to propogate their hatred against Islam.
For instance, before this, the United States of America had propogated that there are weapons of mass destruction (Read more here) in Iraq as an excuse to attack Iraq.
After the attack, no weapons of mass destruction can be found in Iraq. At the annual Radio and Television Correspondents Dinner, February 24, 2004, George W. Bush joked about being unable to find WMD in Iraq, saying "Those weapons of mass destruction must be somewhere", while showing images of himself searching the White House for something.
The truth is that if there really was weapons of mass destruction in Iraq, USA would not have dared to attack them because USA had not done so towards Russia or China. Now, those two countries really does possess weapons of mass destruction.
The latest brouhaha of the film "Innocence of Muslims" which is also known as Muhammad movie trailer and the real life of Muhammad made by Sam Bacile had caused world-wide chaos where Muslims marched in protest all over the world against the vile potrayal of our prophet Muhammad s.a.w.
Surely this is what those people who made the film had in mind because of the brutal reaction from those Muslims who had held violent protest where in Libya it had resulted in the death of U.S. Ambassador J. Christopher Stevens. This will be proof of the propaganda that Muslims are terrorists and barbaric.
And the majority of the Muslims who reacted harshly in retaliation towards the movie had eaten the bait that had been set by those who wanted them to react in the intended way.
But those actions can be guessed because Muslims are really protective of their religion and prophet Muhammad s.a.w.
