AFC were formed after the FA approved the move and it became clear that there was no way to prevent it.
Imagine County had been ground sharing at Old Trafford for a decade prior to getting moved 70 miles and the new AFC County played in Fallowfield. That’s more equivalent distance wise than Ashton. In terms of accessibility Wimbledon to Kingston would be more like Stockport to somewhere like Levenshulme.
And Wimbledon will be playing at New Plough Lane very soon.
The only black mark against AFC (in my eyes) is the treatment of Kingstonian, although Chelsea share more of the blame. AFC are Wimbledon. MK Dons are a stain on English football.
