Spend even a short time in the world of derby and it won't take you long to observe that the sport is in constant movement even off the track. It's growing at such a rapid pace and is attracting the attention of so many across a range of generations. Yet, it often struggles to shake off the yoke of the 1970s version of derby that your creepy uncle remembers.
It seems that derby is a bit cursed by its origins as a theatrical entertainment, and some might see both those origins, and the still-present subculture and style of derby, as thwarting any attempts it (maybe) makes to be recognised as a valid, complex sport.
Some (limited) exposure of derby in the media compounds this issue with obsession regarding the contact nature of the sport, the derby names, the fishnets. This focus doesn't do the world of derby the justice it deserves.
