Yes they did - owlswing - which was the start of the whole discussion.
You're going to have to point out the post in which he said that, because I can't find it. I did find a couple of posts in which he called it soccer and posts in which he defended his use of the term, but no posts in which he claimed everybody should call it soccer.
And where did I ever claim that. Where did I say that this discussion was about someone thinking that everyone should use the term soccer - I didn't. I claimed that this was about the suggestion that football should be called soccer rather than football.
Clearly owlswing thinks football should be called soccer - why - because that is the term he choses to use himself and when pulled up on it by Rhiannon justifies its use.
Now I'll happily accept americans using the term soccer, as this is the accepted term there and using football creates confusion with the game they call football. But there isn't the same excuse in the UK - anyone using the term soccer either uses it in ignorance of the fact that the football community (fans, players, teams etc etc) never uses it and don't like it, or in a kind of belittling and somewhat derogatory manner. Owswing seems to fit the latter rather well.
And my earliest posts on the matter suggested that those that insist on calling the sport soccer (unless they are american) tend to do so because they aren't fans and often in a somewhat derogatory manner. Which was exactly the case in his post.
It's clearly true in his case that he has a low opinion of football but I've never met anybody who insists on calling football soccer, so I can't comment on the general case.
I've met a fair few (in the UK) and they tend to fall into the categories I mentioned above.
