Huh? You objected to Guardian using "scare quotes" or something and I told that this type of abuse happens there all the time. Human rights don't exist.In fact, several of them have been arrested for pulling the same crap in USA http://www.kbur.com/2013/09/20/saudi-princess-scheduled-to-b...
"Scare quotes are quotation marks placed around a word or phrase to imply that it may not signify its apparent meaning or that it is not necessarily the way the quoting person would express its concept. Thus, the quotes are used to establish a use–mention distinction, in a similar way as verbally prefixing a phrase with "so-called". When referred to as "scare quotes", the quotation marks are suggested to imply skepticism or disagreement with the quoted terminology."
You can always narrow a concept to exclude members of a set if you are allowed to declare your preferred definition, but the general use of the word slave obviously includes forced labourers who are being denied wages and held against their will while being worked to death and denied water, to argue otherwise would seem to make an utter mockery of the term.
