I don’t know why this is so hard for you, but the Union didn’t start the war. The South did. And the reason why the South started it was they wanted to keep slavery. Nice try...
I try very hard to stay away from these threads. Having said that, I grew up in California many years ago. Back when we had the best schools in the nation.
My high school US history, government and civics teachers and my college US history teacher believed the Union started the war.
Okay, I’m gone. :)
