As a deeply religious person, I don't like blasphemy. My religion and its holy books are sacred to me. And I understand perfectly well why a Muslim would not care for a cartoon of a naked Mohammed.
But the debates over freedom of speech and the sensitivity of religious feelings also miss the point.
For non-Muslims, the right to blasphemy is also the right to believe. While we may think of blasphemy in terms of the Charlie Hebdo cartoons, each religion is also mutually blasphemous.
