I think you're right - but only to a point. We do seem to be judged by the actions of a minority of cyclists at times but I think that most people are smart enough to realise that the trouble in this case was caused by a person on a bicycle and that not all people who ride bicycles act the same way.
It's a bit like hearing that a pair of bank robbers escaped in a white car. No one believes that everyone who drives a white car is necessarily a bank robber.
