The BBC really just don't like religion... Link will only work today, as it's fact of the day. I'm sure tomorrow you will get something denigrating Islam. Or maybe not.
Of the 13 uses of the word 'laughed' in the Bible: 9 involve people being 'laughed to scorn' (usually accompanied by mocking and/or despising); two are bitter or ironic laughs; and one involves someone being frightened to admit to having laughed ironically. Only one of the 13 references can be reasonably described as cheerful, and that is in Job, one of the most miserable and dispiriting books in the Bible, as he recalls his former happiness before God and Satan conspired against him.
