I'm not going to pretend that this event didn't feel slightly odd to me. The parents, mostly but not exclusively white, looked as if they came from up the hill in Noe Valley, a more affluent area. The market occupies the street in front of the Mission District landmark destroyed by fire early this month, a blaze that left over sixty people homeless. Most of the newly homeless are Latino immigrant families; many are children. This wasn't their march.
On the other hand, I would bet that the sort of parents who bring their kids to this sort of thing are the sort of people who helped raise $180,000 for the fire victims. For all its tensions, San Francisco can still sometimes delight.
