I think you may have him confused with Edison...
Correct. Edison was the prolific inventor in the right place and time for classical electrical discoveries.
While, Ben Franklin discovered electricity but his greatest achievement was signing the Constitution which created the world’s first free republic.
Imagine that, electricity is everywhere, even our Constitution. And the hate America, or hate Whitey folks can do NOTHING to change that relevance.
It is engrained in history, FOREVER.
Tell your leftist teacher to stick that up his nose.
