Hahaha. Never in the history of humanity people have converted due to short comings of their faith. They have always converted because they found the other faith more adaptive to their conscience. For e.g. I was a born as a hindu. But then I kept reading about different religions. Then I decided that I can only have a neutral view point if I dont follow a religion. I did. I see my conscience much clearer than the people who claim to belong to x or y religion.
