Do you believe that people of different religion are still similar in humanity?

Yes. They all have the need to believe in something that is all powerful and on their side. They are human.

They make mistakes, they love, they hate, they live in faith.

Yes, absolutely. I find no difference between individuals because of religious affiliations. I know and believe that all religions lead ultimately to God.

I think all "religions" have good and bad points within their systems which in itself is a mirror of their humanity.

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.
