I saw a group marching up Market Street today behind a banner reading

THE WAR STOPS HERE
and so do you

I was tempted to stand in their path (surely I have as much right to obstruct them as they have to disrupt traffic) and demand an explanation of the last phrase. But I had been on my feet long enough already, had more errands to do, and lacked the energy for a confrontation.

Later: It occurs to me that I’d have been wrong to bring them to a stop; they were moving steadily, in the appropriate lane, and stopping them would only cause a worse obstruction.
