As it turns out your daughter was right and the teachers were wrong. This is exactly how they work. They punish anyone who goes against consensus so the other kids will toe the line if they want good grades. It is done all the way to the PHD level and nobody challenges the theories they want promoted. Pure Junk science to promote an agenda.
Pray for America
I work in the SPED dept. of our local Jr Hi, several years ago I helped a young man write a report on GW. He chose to be against it. I was fearful that his grade would be impacted by his stance. But to my great surprize, after putting together a terrific report, he earned an A and a Blue Ribbon at our county fair.
Maybe this is due to what part of the country I live in and it was just Jr Hi.
