You don't get to choose what words mean in the English language. Soccer is a legitimate name for football and your denials won't change that.
Jeremy - we've been through this on another thread at length.
The term 'soccer' is not and I don't think has ever been an accepted term for football amongst football fans. I have never known a British football fan who falls the sport they follow 'soccer'.
I suspect it never was acceptable, probably because it was coined by a person (Charles Wreford-Brown) who was desperate to keep football as a sport played only in elite public schools and elite universities, to be completely amateur and had a distain for spectators as he believed that the sport should only be played, not watched. Not surprising then that the teams and their fans gaining prominence during that time (1880s and 1890s) that were professional, working class, often from tough northern and midlands communities would saw Wreford-Brown as a hate figure and almost certainly hated his term 'soccer' which was synonymous with his version of the game (elite, amateur) than the game that took hold.
Bottom line, in Britain if anyone uses the term 'soccer' you know straight away that they aren't actually a football fan and often they are not just neutral towards football but look down on it, thinking it to be lesser than rugby or other sports.
