I think you have possibly answered the question for yourself in this post and the several which follow it.
I live near Chorley, have friends who support Chorley and the majority of local football fans will keep an eye on their results and how their season is progressing. Some, including myself, even go to watch a game from time to time. Similarly people have an interest in Stanley to which you can add there is a touch of "romance" associated with the club.
I've a passing interest in several other clubs for varying reasons; Wimbledon (of old), Charlton, Yeovil, Aldershot Town, Hereford United, York City, Blyth Spartans. Following the exploits of Colne Dynamoes was always fun. I'd hazard a guess the vast majority of fans are similar. I can see why you wouldn't appreciate or understand this.
If Stanley go up I won't be celebrating wildly but I'll smile quietly to myself, feel pleased for their fans and appreciate how they feel. It's what football fans do............
