I too detect some intra-communal snobbery in the cycling world and find it as unhealthy as it is unhelpful.
I abhor any form of discrimination, so this sort of thing is bound to get to me.
The worst snobbery comes from the new-to-cycling, team-lycra, carbo-fantastic brigade. They should appreciate that if there were a scale of cycling merit, they'd be at or near the bottom of the pond. Maybe even in the silt on the pond bed.
I feel slightly sorry, on the other hand, for commuters on folders. They are somehow excluded from any community feeling by their fellow riders. This is quite wrong and I disapprove thoroughly. Even though they are the worst possible type of so-called cyclist.
Then there are the mid-20s, baggy-shorted, tousled-hair MTB mob.... They are as bad as all the rest, if not worse. Probably as bad as each other and at the same time significantly worse. Certainly no better than they ought to be.
Some are close to them in moral and social delinquency. Others might even outstrip them. It is all very, very sad.
So... Accepting (as I now quite suddenly do) that there is a place for snobbery in cycling and that it is just and right and proper, I place all the above below plankton and only slightly above fixter-hipsters on their brakeless, skip-find, death traps with chains in primary colours.
I write the above to inform and elucidate, not to provoke a reaction.
I do not include myself (on roadbike, MTB or fixie) in any of the groups on whom I pour justified scorn.
