i think you misunderstand me.
i've been riding and helping to facilitate critical masses at home and away for several years now.
and safety (for riders and motorists) is one of my highest priorities (next to fun and bike advocacy).
yes when the group is big enough we will have to hold the intersection and get the whole group across.
i am usually one of the guys making sure the group stays safe and together.

my biggest concern here, after encountering much of it firsthand,
is the recklessness some riders come to critical mass with.
these riders create conflict with motorists, rather than let the ride speak for itself.
these riders can make critical mass more dangerous for themselves and other riders,
and this is something i do not approve of.
