I'm getting fed up that people take these complaints seriously. IF 5 million people have seen the advert, and 8 people have complained, literally ignore it. For a widely seen ad frankly, any people involved, so M&S, and any trading standards, complaints departments type people should only even be registering this as close to a problem if you were talking about 10,000-100,000's of complaints.
8? IF we start withdrawing ad's, and stories, and tv shows and music over 8 damn complaints, well nothing would get shown. Almost everything in the world is offensive/irritating to at least someone, the more we blow these things out of proportion and start caving in to a ridiculously small minority, the more people will complain thinking they can get rid of the things we don't like.
This news story should have been a joke, or laughing at the 8 people with no lives, rather than debating if the ad should be investigated and maybe pulled.
