Seems like old times.
I don't know if this is related to the Bronx hate crime or not (I doubt it, this event seems to have been in the planning for days), but a flash mob suddenly lay down in the middle of Grand Central Friday night and blocked traffic. They unfurled a big yellow banner that read "End Homo - Transphobia Apartheid!" One person read the names of people killed recently by hate crimes or driven to suicide by bullying while the others shouted back each first name. The whole thing lasted about 3 minutes.
Our side doesn't need money from the Koch brothers, or from the Chinese or the Saudis laundered through the Chamber of Commerce, or need the help of Murdoch's media empire, to pull these things off.
Also, I'm struck by the wide range in age and ethnicity of the people participating, very different from those largely monochrome gatherings regularly featured on TV and so well funded.
