Why 95% of SGI-USA members eventually abandon the Lotus Sutra

"Our teacher said: Hearing the Sutra of the Lotus Blossom of the Wonderful Dharma is called 'security and peace in the present life' and also 'later birth in a good place.' [This passage] is immediately preceded by the words, 'Having heard this Dharma.' 'Heard' indicates the ordinary worldling at the stage of verbal identity. In hearing the Wonderful Dharma, one hears that one attains Buddhahood in this very body. This is the meaning of the passage, 'One who can hold [this sutra] thereby holds the Buddha's body.' Because one hears, one holds, and therefore the three kinds of powerful enemies arise; their coming fulfills this passage's prediction of 'security and peace in this life.' There can then be no doubt that one is a practitioner of the Lotus Sutra, [for] we read in the sutra that a practitioner of the Lotus Sutra will encounter such grave persecutions. And by encountering grave persecutions, one's attainment of Buddhahood indicated by 'later be born in a good place' is assured. So how can one not feel secure and peaceful in the present? 'Later birth in a good place' is clearly expounded in the 'Devadatta chapter.'" - ONGI Kikigaki

Is there any wonder why 95% of all SGI USA members have abandoned the Lotus Sutra? They are rarely ever taught the process of attaining Buddhahood, instead, they seek for mere trinkets.
