You're stating two different points.
1. Freedom of Speech is for everyone.
2. Why it isn't extended to terrorist who have don't differentiate from civilian and military targets.
Freedom of Speech doesn't extend to "Yelling fire in a crowded movie theater."
There's freedom of speech, speaking your mind, ie verbal. Then there's freedom of expression, speaking your mind through other forms of medium, ie cartoon, tv show etc.
Freedom of Speech or Expression, doesn't allow you to draw appalling cartoons of a Prophet regardless of the Religion of his modern followers. Regardless of a rebuttal that all religious figures are "fair game". There's a difference between a Prophet, a Rabbi, and the Pope.
1. Are you asking if people who support the TTP would support the terrorism in France? Answer is simple, yes. Those people are so far uneducated that even their off-spring are a lost cause for education.
2. The french terrorist wanted "justice" for the Prophet Muhammad (PBUH). The TTP wants a Sharia State, where the "educated" religious figures can do whatever they want, but the people are bound by a strict "Sharia Code" only they are bound too.
