That's a very different starting point to mine, which is to get as many people on bicycles as possible. A lot of the argument seems to arise from what campaigning and activism mean. When I began riding any distance in the 70s and joined organisations like the CTC, I assumed it was to protect cyclists' rights and increase the number cycling. The civilising effects of bicycles on a city are just one part of that agenda.
Most people may well live in cities, if we take cities to mean suburbs and liminal outer zones that have very little in common with true city living but even then a large minority do not and the more vocal aspects of campaigning tend to look exclusively at urban resolutions which IMHO, do not and cannot apply to cyclists travelling outside the city.
When the agenda moves away from bums on saddles all manner of vying interests and utopian ideals begin to sway the debate and how people should live, not how they do takes on an evangelical tone with all the absolute rights and wrongs that go with it.
My local pub has just begun a series of rides around other local boozers, 15 hilly rural miles on summer evenings. A couple of roadies, various mountain bikers and a bunch men and women who haven't ridden since childhood. Their efforts may be all but meaningless on a campaign scale but they're a constituency of riders who require safety like every other cyclist and the security of activists working on their behalf.
Why? And why should anyone who doesn't already see cycling as an end in itself care about such an objective?
