No you didn't take it too far - you did the right thing but I will say if you don't stand for yourself no one else will and you'll be taking peoples no good nic for the rest of your life. ( also sometimes it pays to try to be friends with people as they may remember your kindness long after school has finished) and I'd like to contribute what's done is done.
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.
