Salamun'alaikum Warahmatullah. What makes sufism a heresy?

Both are correct. A Sunni can be a Shia and a Shia can be a Sunni. The word "Shia" refers to those of Persian descent.

Thus a Christian, atheist or Muslim who is Persian will refer to themselves as a "Shia". The Arabs and "ansar" are thus "Sunni" by default as they are not Persian. Their beliefs in Islam are exactly the same - it's their culutre, language and politics that differ.

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.
