I will certainly defend someone's right to commit blasphemy. Burning a Qur'an is blasphemous from the point of view of Islam...and you have every right to do it, just as you have every right to commit blasphemy in the eyes of Christianity, Hinduism, etc.
Needless to say, such acts shouldn't be supported by the government in the form of art grants...but neither should they be prohibited in any way.
(Of course, the government shouldn't be supporting the arts at taxpayer expense in the first place, but that's another subject)
I don’t know your gender, but if someone waved a Photoshop of your spouse appearing in a jar of pee in your face, wouldn’t you take that as fighting language?
