Because I read a thing that made me cranky.
Professional (meaning, academic) historians have nothing to do with what public schools teach their nation’s children. At least, not in the US (though I’m pretty sure this extends to other nations). If schoolchildren don’t know about a Really Important Thing, they don’t know it because their educational system is failing them, not because professional historians aren’t doing their job.
Let me tell you, if professional historians had a say in k-12 history education, I wouldn’t have students in 200 level courses in a university students need a 4.0 to get into telling me that slavery wasn’t that bad because America was really good at breaking down barriers.
