I don't support CM because, excluding the proverbial exceptions which don't disprove the general rule, it strikes me as an exercise in hypocrisy. You don't earn respect from others by intentionally sending out disrespect to those same people. You can't induce more lawful driving awareness by motorists by participating in a demonstration of unlawful cycling behavior, e.g. ignoring red lights, 'corking' intersections, hogging all available lanes, etc.

In an A&S thread on this same topic, someone made the incisive observation that, paraphrasing, what CM participants think about CM doesn't really matter because ultimately it is their actions which will count to the non-cycling target audience. Intentions are invisible; motorists will remember only being unduly delayed by an intentionally disruptive 2-wheeled mob disregarding traffic laws and/or common sense & courtesy.

I believe pushback is coming. I hope too many people aren't surprised when it arrives.
