The problem with blasphemy is obvious: One man's blasphemy is another man's holy writ.
In the United States the Constitution prohibits Congress from enacting legislation regarding religion. That was a radical principal when it was written down in setting up a nation. Most nations of the world in one way or another favor a state religion, the Communists not excepted, because they treat Communism as THE state religion.
Reading down this thread, which I find quite enjoyable, I keep remembering Thomas Paine's famous riposte. After he said, "I know not what course others may take, but as for me, give me liberty or give me death". And when others round him hollered "Treason!" he responded: "If this be treason, make the most of it!"
What goes through my mind is, on Stephen Fry's behalf: "If this be blasphemy, make the most of it!"
