How to refute several important Gakkai talking points

When SGI members see their ugly face, they invoke the Lotus Sutra Chapter 13 about hatred and jealousy in the Latter Age. The key to refute this argument is to demonstrate how their doctrines and practices deviate from those of the Lotus Sutra and its votaries. Since that is so, the Lotus Sutra is certainly not talking about them as its votaries. 

Another problem, when we point out their reprehensible behavior, they either trot out Ikeda's guidance on compassion and place the blame on human imperfection and failing to follow the mentor's guidance or they again invoke the Lotus Sutra [Chapter 10] and writings of Nichiren that it is slanderous to point out even the major misdeeds of the votaries of the Lotus Sutra. Then again, it is worthwhile to point out that they are certainly not votaries of the Lotus Sutra because votaries uphold and protect the Lotus Sutra while they abandon and defame the Lotus Sutra [and we can cite examples] or we can point out that, at the very least, their teachings have no power to elevate the human condition We may also highlight that Nichiren Daishonin always placed the blame squarely on the shoulders of those at fault. 

Sometimes they proclaim that we can't possibly understand the great wisdom and compassion of their mentor and top leaders, that what we see as black is actually white. Then it is wise to point out the principle of thusness or suchness is not altered in the slightest by human perception. 

Their mentor is particularly reprehensible in light of the Lotus Sutra and the behavior of the Buddha and Nichiren Daishonin because he has taken something noble and turned it into something base, his words, failing to match his actions, and both his words and actions failing to match those of the the Lotus Sutra, the Buddha, and Nichiren Daishonin. The general members too, except for the most neophyte, are complicit and can't hope to escape the horrible destiny that they are creating for themselves and others. In real Buddhism, there is the principle of personal responsibility. Even SGI mind control can't absolve them of turning the Lotus Sutra into a cult of personality and hatred of the authentic teachings of the Lotus Sutra and Nichiren Daishonin
