I would say that it is a call the parent has to make. Youtube does it best to keep adult content locked for only those who verify their age. However a lot of the videos are aimed at men with flexible women in small, tiny swimsuit doing scrunchies.
They even have some body paint videos that can be viewed without age confirmation. Therefore I would hope to keep my children off of youtube for the most part until they reach middle school. At that point I would let them use it, as it has many valuable resources as well.
But this is really up to the parent.
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.
