Response to a believer

Me: Nearly everything you learned in the Nichiren Shoshu and the Soka Gakkai is wrong and half of what you learned in the Nichiren Shu, Honmon Butsuryu Shu, and Kempon Hokke. 

Believer: If just half of the truth of what I learnt from Nichiren Shoshu, Soka Gakkai and the rest can be put to good use in helping to see through the nonsense, well then that would be a good thing

Me: Its like a bike accident in which one hits his head, is in a coma for a couple of weeks, and then starts wearing a bike helmet.
