That's... uh... certainly interesting. Can you elaborate a bit? Was Edison particularly pro-feminist? If so, how did this translate into modern day popularity? What's the process there? Why would this come down to the personal opinion of schoolteachers? Would they, as a group, have enough of a consensus on this that it'd influence Edison's popularity? Why would that consensus take this particular part of Edison as a primary reason to view him as a positive role model?
