SGI/Nichiren Shu are both proponents of Interfaith

Remember, they both fail to practice as Nichiren Daishonin teaches..."The exclusive faith and practice of (Namu) Myoho renge kyo." There is no interfaith in the Lotus Sutra Buddhism of Nichiren. Yet, they have the nerve to call themselves "Nichiren Daishonin Buddhism". One can not chant the Daimoku and expect benefit and protection with their warped faith.

"Now in this latter, evil age, great evil arises less from secular wrongdoing than in connection with the doctrines of the religious world. When people today, who are unaware of this, endeavor to cultivate roots of good, events that lead to the ruin of the world occur all the more. Although superficially it may seem to be an act of good to provide support to the priests of the Tendai, True Word, and other schools of the present age, in reality it is a great evil surpassing even the five cardinal sins and the ten evil acts."

"Question: As I understand it, a teacher is someone who has grasped the central meaning of the sutras and treatises and who writes commentaries explaining them. If that is so, then it is only natural that the teachers of the various schools should each formulate doctrines according to their own understanding, and on that basis write their commentaries, establish principles, and dedicate themselves to the attainment of enlightenment. How could such efforts be in vain? Toinsist that the Lotus Sutra alone holds the position of absolute superiority is to adopt too narrow a view, I believe.

Answer: If you think that to proclaim the absolute superiority of the Lotus Sutra is to take too narrow a view, then one would have to conclude that no one in the world was more narrow-minded than Shakyamuni Buddha. I am afraid you are greatly mistaken in this matter..."

“These various sutras expound partial truths such as ‘the mind itself is the Buddha, and the Buddha is none other than the mind.’ The Zen followers have allowed themselves to be led astray by one or two such sentences and phrases, failing to inquire whether they represent the Mahayana or the Hinayana, the provisional teachings or the true teaching, the doctrines that reveal the truth or the doctrines that conceal it. They merely advance the principle of nonduality without understanding the principle of duality, and commit an act of great arrogance, claiming that they themselves are equal to the Buddha. They are following in the tracks of the Great Arrogant Brahman of India and imitating the old ways of the Meditation Master San-chieh of China. But we should recall that the Great Arrogant Brahman, while still alive, fell into the hell of incessant suffering, and that San-chieh, after he died, turned into a huge snake. How frightful, how frightful indeed!"

"The sutras expounded prior to the Lotus Sutra cannot lead toBuddhahood because they are provisional and expedient teachings that separate reality and wisdom. The Lotus Sutra, however, unites the two as a single entity. The sutra says that the Buddhas open the door of Buddha wisdom to all living beings, show it, cause them to awaken to it, and induce them to enter its path. By realizing this Buddha wisdom, one attains Buddhahood."

"The non-Buddhist schools of such men as Vatsa and Vaipulya, which appeared in India after the Buddha’s passing, are even more wrong in their views and more cunning in their doctrines than their counterparts before the Buddha [because they borrowed ideas from Buddhism]. Similarly, since the introduction of Buddhism to China in the Later Han dynasty, non-Buddhist views and writings have become even more wrong and cunning than the pre-Buddhist writings of Confucianism that deal with the Three Sovereigns and Five Emperors of antiquity. Also the teachers of the Flower Garland, Dharma Characteristics, True Word, and other schools, jealous of the correct doctrines of the T’ien-t’ai school, brazenly interpret the words of the true sutra in such a way that they will accord with the provisional teachings."

"In Tung-ch’un we read: “Question: While the Buddha was in the world, there were many who were resentful and jealous. But in the age after his passing, when someone preaches this [Lotus] sutra, why do so many oppose that person? Answer: It is said that good medicine tastes bitter. This sutra, which is like good medicine, dispels attachments to the five vehicles and establishes the one ultimate principle. It reproaches those in the ranks of ordinary beings and censures those in the ranks of sagehood, denies [provisional] Mahayana and refutes Hinayana. It speaks of the heavenly devils as poisonous insects and calls non-Buddhists demons. It censures those who cling to Hinayana teachings, calling them mean and impoverished, and it dismisses bodhisattvas as beginners in learning. For this reason, heavenly devils hate to listen to it, non-Buddhists find their ears offended, persons of the two vehicles are dumbfounded, and bodhisattvas flee in terror. That is why all these types of people try to make hindrances [for a practitioner of the Lotus Sutra]. The Buddha was not speaking nonsense when he declared that hatred and jealousy would abound.” _ The Opening of the Eyes
