Don’t all lives matter—not just black lives?

Of course all lives matter. The point dolts like you don't get is that in many situations for a long time black people, mostly young men, were being killed and nothing substantive was being done to even investigate the deaths. Using "Black Lives Matter" is a way of pointing this out.

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.
