Is it time to start calling out bad cyclists?

By 'bad cyclists', are we actually talking about people who have a prejudice against cycles? Are they likely to set up a political party that promotes cyclism, dishing out thinly veiled hatred about washing machine programs or the progression of the seasons or whatever?

I think it's about people who are 'bad' at being cyclists. Like me, I hardly ever ride a bike and make excuses as to why I don't use one as a mode of transport. As opposed to regular cyclists who are simply bad at riding their bikes: they wobble, skid and ride like monkeys humping beach balls. But they do it every day.
