What began as a well-intentioned playdate for kids of color at a Bay Area elementary school quickly spiraled into something very different.

That playdate on August 27th sparked anger online, as right wing groups seized on it to cry “racism,” and that eventually led to a bomb threat today that forced the evacuation of the school.

We’d love to think this is an isolated incident, but sadly, this kind of viral hate is more and more common, and often leads to terrible violence. We’ve seen it at schools and universities around the country, in mass shootings from coast to coast, in last week’s killing of a shopkeeper who displayed a Pride flag outside her store in Southern California.

Thankfully, no one was hurt today at Chabot Elementary School in Oakland, which was safely evacuated before classes even began. Police spent hours searching and found nothing dangerous. But the incident sent hundreds of kids home for the day, canceling a day of school, and terrified and terrorized a community, which will now have to come to grips with this and all its fallout, and it all started because of one parent’s post on social media.
