European Parliament Platform for Secularism in Politics - Freedom of Speech: the Right to Blasphemy?

In the aftermath of the Charlie Hebdo attack, the discussion on the scope of free speech has flared up again. Does the right to freedomof speech also include the right to blasphemy? The purpose of this meeting is to have an open discussion on the unlimited right to freedom of speech on one hand, and the desire to prohibit blasphemous or religiously hurtful speech on the other hand.
