You're right. It's called a tu quoque fallacy, an attempt to excuse one's behaviour by saying the opponent did it too. I just used one (sort of) deliberately in response to a 'question' about the allegation that Clinton made saying Trump is ISIS' best recruiting tool, which they of course have turned into some notion that Clinton has seen a video to that effect, which she didn't say.
But let's say she did. She ain't apologizing because Trump won't apologize for his lie about seeing thousands of Jersey City people celebrating 9/11, which as we know, is a big fat lie. That's one of the many things Trump's campaign does.
It lowers the tone of discourse and opens the door for everyone to double down on their lies. Tu quoque, it's terrible...but most folks are too stupid to identify them and worse, if they do, they don't care. Whatever scores hollow points.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
