Non-scientologists, if scientology isn't true why do countless people believe it is?

This is not an accurate claim. The Church of Scientology is primarily engaged in administering and delivering Scientology to it's parishioners. It is the International Association of Scientologists ( IAS ) that does all the external Charity work via it's various very effective and popular global campaigns.

The IAS administers the charitable humanitarian donations from individual Scientologists and other like minded humanitarians and executes these global campaigns. Many also volunteer and donate their time and participation in addition to any financial donations they make.

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.
