I regularly attend iBike London supported Kidical Mass rides in London supporting them as a marshal. The middle of the mass passes through red lights, after we, as marshalls, have corked junctions. I help facilitate children cycling safely with their friends on occasional Saturdays. Technically illegal. On the other hand we've had Will Normal (London Walking and Cycling comissioner) give us a speech at the start of last year's kidical mass ride, knowing full well how we operate such rides.
I had some woman at a speed dating event a few weeks ago heavily imply that Kidical Mass was unenthical (and thus so was I) because it breaks the law. I think it's unethical to build a world in which children can't get around safely by bicycle for the benefit of drivers
