As somebody who was extremely blessed to have a couple of pro-American, patriotic (read 'Unbiased' and 'honest') history teachers when I was in school (ca. 2014) I would just like to say: Thank you. It was the second greatest thing to happen to me behind being born to the parents I was born to. Keep doing what you're doing and take solace in the fact that you are doing the right thing, no matter what people say.
