A bit more about the march
When I arrived at the site of the march, I was in full distanced-irony mode. I stood off to one side, a cool and detached observer, taking occasional photos and wryly noting just how few people were there. (At a very rough guess, I'd say about 2000; for contrast, the San Francisco march the next day apparently had about 100K to 200K, depending on whose numbers you believe.) Given the small size of San José's Pride marches, the small size of this rally didn't surprise me much.
But the aforementioned Raging Grannies song started to get me into the right mood—I smiled despite myself. Before long, I noticed that although the crowd was predominantly white and (judging by appearances) upper-middle-class, as usual for liberal events in the South Bay, the average age wasn't nearly as high as usual. In particular, the organizers of the event appeared to mostly be college students (mostly, I gathered, from the local community colleges), and they were sincere and well-spoken and passionate and did a reasonably good job of energizing an initially somewhat diffident crowd. And only a couple of them were white. And y'know, no matter how unlikely it is that this march had any effect on whether there'll be a war, those students gave me hope for the future. There are student activists in San José, and they care enough to organize peace marches. I think that's cool.
Some of them were apparently associated with Silicon Valley De-Bug (subtitled "The Voice of the Young and Temporary"); looks like there might be some interesting stuff there.
