Well, you quote a part of a film where a gay man is explaining why he likes the artistically decorated pages of a Quran from the 14th century. You use the actions of ISIS and other fundamentalists to say that the appreciation of that religious art is invalid. The catholic church is another institution that is famous for its stunning religious art in locations around the world.

If you're going to use religious fundamentalism to say that we shouldn't appreciate a particular area of religious art, then the same policy should be taken across the board, whether it is Christian, Muslim, or any other religion which has been used as a justification for atrocities.
