While I quite agree that politically correct objections to certain language/symbols can very quickly veer towards the absurd, there are broader considerations on this topic that deserves a degree of concern over and above the appearance of the apparent jingoistic bigotry straining to gush forth on this thread from the anti-political correctness brigade.
The earlier, somewhat sarcastic, point that suggested banning the nickname 'Pirates' for politically correct reasons, quite effectively illustrated how absurd the pc debate can be. The same could equally apply to, say, the nickname Vikings, for all the violence popularly associated with those northern 'brutes' (just forget about the fantastic art they brought with them, eh!), though if you've ever had a saturday night out in Hull city centre you'd know that never was a speedway team more appropriately named!!
Yet, while the posting above states that it's only the speedway community that is aware of the more politically in-correct nicknames (in this thread's case, Bomber Harris) and therefore doesn't really matter, we ought to be conscious that speedway does not exist entirely in some sort of cultural bubble.
For example, I recently introduced two brand new people to speedway who have a wide range of interests, both are humorous and well educated. The meeting happened to involve Somerset and they were both absolutely flabbergasted by their Rebels nickname and at how proudly the fans brandished their confederate flags. Cultural symbols do matter and my companions were left wondering just what kind of people would so happily associate themselves with such a strong symbol of southern slavery and the KKK? They're aware of Bristol's history of participation in the slave trade but just how big is the Klan's presence in the west country these days, they wondered?
During an initial period of discomfort, and extended period of p***taking, I could only reply that those people waving that flag would be speedway people who really didn't give a toss about the world beyond the fourth bend. Sorry to say, but that didn't sound like much of a mitigation to them!
Anyway, you'll all be glad to know that these two debutants thought the speedway was thrilling, but whether they'll decide to venture back into our cosy little cultural bubble remains to be seen!
Would it matter if they didn't return, anyway? Well, a speedway club that represents a city with quite a high number of young people from a different cultural background, Oxford, has just gone belly-up, so perhaps the image that speedway projects does matter, after all!!
