The American wank does get annoying, especially when it becomes a 'Americana holier than thou' one. I also hate when history is removed or altered just for the sake of making one particular side look good.
I was history professor back in Russia and I possess my doctorate for 19th and 20th century European history. It just unnerves me to see a television show about history get history wrong.
As you and anyone should. It's a shame to see of how more american school system is willing to omit information, facts, and other important notes in history.
