The SGI does the EXACT same thing as the Five Senior Priests yet they most forcefully criticize them, their nose in the air.

The "EXACT same thing" is that they compromise the teachings "to protect" their believers [members]. What they have ended up doing is not only destroying the teachings but their members [by protecting them from persecution and developing the heart of a lion]. The problem we have with Nikko is that, although he preserved the teachings, he led a relatively sheltered life in Fuji, never having had to deal with direct persecution of his believers, his nose in the air like SGI's.
