You are free to believe anything. You may believe in Santa Clause or the Easter Bunny. There is about as much proof of the authenticity of the DaiGohonzon and of Ikeda being the Buddha of the modern age as there is for Santa Clause. Who am I to question your beliefs? Why should I even care that you embrace a fairytale rather than experience the true greatness of the Daishonin's teachings? Hell, if you die with a smile on your face singing Forever Sensei, who am I to try and shake your beliefs, even should the Lotus Sutra and Five Major writings of Nichiren point out the heresy of your beliefs.
