If I trust the school and teachers enough to send my kid to school, then I should trust them to provide appropriate materials. Allowing parents to pick and choose may leave us with not much of anything left. Anyone can find offense with just about everything these days.
Defend students right to learn. All inclusive. Equality.
People don't want to sensor what the kids wear or what they see on their phones while at school, but they want to pick apart every tiny sentence of what their kid is being exposed to in the classroom. What parent has time to do that anyway? We are suppose to trust our educators.
