I said “from Christian point of view”.
What you described as “blasphemy” is a Muslim point of view.
Which tell us that what is “blasphemy” is very much religion-specific. And a person expressing his or her religious views is always “blasphemous” from point of view of a different religion.
This means that any objection to people on the basis of “blasphemous” speech and religious sensibilities is an affront to freedom.
One can’t object to, e.g., images of Muhammed or “Life of Brian” movie — if one does, one is undermining freedom of speech.
