"Why is there is no mention of the Soka Gakkai’s presence in society and the world of Buddhism in your article about Buddhism...?" -- SGI member

Response: Perhaps there was no mention of Soka Gakkai in this article because Soka Gakkai is Ikedaism, not Buddhism. Why would the author of the article include Islam or Brahmanism in an article about Buddhism?
