Saw something online about this yesterday, and it suddenly occurred to me that there is only one narrative being backed by the MSM - the parents are wrong, they're lying about what's being taught, and it's all being whipped up by agitators. All of that is probably true, but then I thought about what's been slipped in under the radar. We know about some of it from that clergyman who, IIRC, resigned as a school governor.
It would be interesting to know what proof the protestors have, of their claims.
