I don't have a football.It always astounds me on threads like this what effort people will go to in order to do the online equivalent of a passive sneer of disapproval at the subject matter. Like most fairly adjusted people, if I see a thread about which I have no interest (say, cats, or reality TV, or electric bikes), I'll just eschew that thread altogether and I'll click on other threads and even consider commenting, only where the subject matter piques my interest.
Other people though....
"Hmm, a thread about football eh? I've no interest in that sport whatsoever, but BOY I can't wait to click "reply" and tell everyone just how much it doesn't interest me!" Cue at least three lines of text, explaining in detail the extent it doesn't interest them.
It's really perverse behaviour. For other examples, see any car or TV related threads, and the associated "Pah, I don't even own a car / TV" replies.
