I think that most of the nay-sayers of CM are those who have never been to one -much less go every month.
Many of folks who really get their knickers up in a bunch about it are the type of folks who are boot-licking badge-worshiping holster-sniffers. I guess the world takes all types. Smash authority -don't bend your knee to it. It's always been a vocal minority that has been the motive force behind any change in paradigm.
Change doesn't happen without people acting out and breaking the mold. The meek really do not inherit the earth -that's simply fiction.
But in the end, those who think that CM should be different and the particiapants should act differently should just go and help influence the behavior of the event rather than sitting at home complaining about how other people are acting in public. Critical Mass is a leaderless, open, and all-embracing movement. Nobody is going to tell you to go home or that you can't ride the public streets during CM with the other bikes. That's the whole point. If you don't like what CM is all about then get out there and help make it something you think it should be -rather than that which you have a problem with.
Because if you sit at home they are going to do their own thing and not listen to you. It's that simple. Fail to participate and your voice does not count.
