I'll leave it to you, Coprinus, to decide whether you are indeed a pretentious twat; but you appear to have a thick skin about an activity you are passionate about, which is a good thing!
I'm personally undecided about CM; on one hand, I'm for anything that involves getting on my bike; on the other, I'm unsure about being involved in what seems to me to be a silly display of civil disobedience...but then, our annual, club-sponsored "Chilly Challenge", a Jan. 1 ride/chili-cook-off, isn't too different, with civility and observation of good road manners left at home.
I may have to just check out a local CM ride, and decide firsthand. I will say this -- I won't be a ringleader for the 'outlaws'.
