Do yourself a favor, and read some of the masterpieces written by former communists. Two short/easy read pieces are Dedication and Leadership by Douglas Hyde and Darkness at Noon by Arthur Koestler.
You will sooner or later want to read Witness by Whitaker Chambers; this has to be one of the most poignent and influential autobiographies of the 20th century. It is also one of the very few books that kept me up 'til 3 a.m. several mornings in a row, despite having a full-time job! (the other was Gulag Archipelago)
I pray we may be equal to the opportunities when Islam falls. Back when SHintoism was discredited, Douglas MacArthur asked for a thousand missionaries. He got a few -- and a whole lot more industrial gurus, like the justly renowned Edwards Deming. Today, Japan has about 1% Christian population, and a powerful public culture of materialism.
Thank you, kindly, but to what end? You have proved my point!
Why do you think, despite McArthur's efforts, there's barely 1% of Christians in Japan, but the country en-masse changed their political ideologies?
