SGI are evil milkmaids who add a lot of water to the milk of the true teachings

"And the ninth volume of the Nirvana Sutra, speaking of the propagation of the Lotus Sutra, states: 'After I have entered nirvana, in the last eighty years before the correct teaching has passed into extinction, at that time this sutra will be widely propagated throughout Jambudvīpa. In that age there will be evil monks who will steal this sutra and divide it into many parts, losing the color, scent, and flavor of the correct teaching that it contains. These evil men will read and recite this sutra, but they will ignore and put aside the profound and vital principles that the Thus Come One has expounded in it and replace them with ornate rhetoric and meaningless talk. They will tear off the first part of the sutra and stick it on at the end, tear off the end and put it at the beginning, put the end and the beginning in the middle and the middle at the beginning or the end. You must understand that these evil monks are the companions of the devil....

“For example, milkmaids sometimes add a great deal of water to their milk. And these evil monks do much the same. They mix in worldly sayings, thus presenting an erroneous version of the sutra and making it impossible for large numbers of living beings to expound the sutra correctly, copy it correctly, apprehend it correctly, pay it due honor, praise, offerings, and respect. Because these evil monks are concerned only in gaining profit and support, they are incapable of widely propagating this sutra. Few are the places they reach in their various preaching excursions, and these are not worth mentioning. The impoverished milkmaids go from place to place selling their watered milk, but although one may make gruel with it, it lacks the real flavor of milk. And this great vehicle scripture, this Great Nirvana Sutra, is like this. As it is passed from place to place it becomes increasingly thin and insipid until it has no flavor at all.

'But though it has no flavor, it is still a thousand times superior to the other sutras, just as the flavor of the watered milk is a thousand times superior to bitter tastes. Why is this? Because this great vehicle scripture, this Great Nirvana Sutra, is the finest of all the sutras that the Buddha preached for his voice-hearer disciples.' (This is the tenth passage.)"
