Why don't you uphold the Buddha's golden words rather than the opinions of others?

"The greatest deception men suffer is from their own opinions." -- Leonardo da Vinci

"The most important thing in practicing the Buddhist teachings is to follow and uphold the Buddha's golden words, not the opinions of others." 

The SGI, NST and Nichiren Shu embrace the opinions of others and fail to uphold the Buddha's and Nichiren's golden words. Why don't you determine to do so?
