Freedom of expression is considered the most significant characteristics of a liberal society, while it's often in conflict with religion and politics. In early 2015, a huge controversy was raised in the wake of the tragic attack on French satirical magazine Charlie Hebdo: where to draw the line concerning freedom of expression and religion? In France, the answer can only be found through reference to French laïcité (“secularism”). This paper will try to clarify the meaning and function of the principle and how it is applied to freedom of expression and religion issues. Inevitably, it will distinguish between the legal parody as a form of free speech and hate speech, to know whether the law could resolve disputes or deepen prejudice.
