It's not like they didn't know.

One paper from 2019: "Kaolin alleviates the toxicity of graphene oxide for mammalian cells " and one from 2014 "Assessment of the toxic potential of graphene family nanomaterials". There are plenty moar where these came from.

From the 2019 paper: "However, graphene oxide reveals toxicity to some cell lines through an unidentified mechanism."

From the 2014 paper: Graphene, graphene oxide, and reduced graphene oxide elicit toxic effects both in vitro and in vivo, whereas surface modifications can significantly reduce their toxic interactions with living systems.

Woke Kindergarten, a group describing itself as committed to “abolitionist early education and pro-Black liberation,” created the video.

The minute-long video says that all people deserve to feel safe in their bodies, schools, and community. “Why do some people feel safe with police and others don’t?” the narrator asks.

The video concludes by saying it’s everyone’s job to help people “who are being treated unfairly,” while showing a picture of a Black Lives Matter protest.

"This school board has no right to rip personal responsibility away from the hands of its citizens," he said. "The family should always come before the government. You do not know better than the parents in my district (North Carolina’s 11th Congressional District). You do not have a right to slam down mandates upon children of Buncombe County that fly in the face of scientific reasoning."

He added that the greatest threat to schoolchildren today doesn’t come from the coronavirus.

"It comes from woke government officials like you who think they are all-knowing and all-wise," he told the board, prompting applause from the audience.
