"... by their fruit you will know them".
I think to someone that has been hooked by the BKs, no philosophical argument will awaken them. I don't think people fall for The Knowledge (I think, in the West, BKs don't even really believe in it all or find it a bit of an embarrassment).
They fall for the experience which, to some, is very deep and intoxicating, at least to begin with.
People say that the PBKs are made up mainly of disaffected BKs. BKs that have had some bad experience in the BKWSU but still want to believe and live the lifestyle. Their leader Virendra Dev Dixit offers a different interpretation of The Knowledge and they try to make sense of all the apparent ambiguities and contradictions and they still defend it as being "The Truth" 100%.
It's just that they believe God speaks through the mediumship of Virendra Dev Dixit now.
In such instances, perhaps it is good for them to look at and ask why, if this is God, such failures happen. Perhaps a basic human reasonableness can be re-awoken through disgust at someone so obviously wrong ... like lying to parents why their daughter died.
However, one needs to be careful. Their are some in the BKs who are livid at the PBKs and a very ungodly war of disinformation and accusation has been used them for nearly 40 years.
According to the BK "God" and The Knowledge, the BK family is one and yet here it is ... split in two. According to the BK philosophy, this cannot happen, they are the only pure religion from which all other religions are inspired. And yet, here they just like all other religion splitting into schisms.
The PBK situation interests me because it also highlights how the BKWSU leadership desires a total monopoly over their faith and does not tolerate dissenters and even reformers. One could argue that Virendra Dev Dixit was at least a reformer, trying to take the BK back to its roots ... if only another fallible human being. On the other hand, you could just say he is another broken victim who has gone a little mad and has become the BK's madness projecting himself at Lekhraj Kirpalani's successor and the current medium of God ... or someone that saw a chance to set up his own gurudom by mirroring the BKs' model.
We've covered the BK philosophy so many times. There is so little to it that all that is left is to keep documenting the terrible and stupid things they do in order to warn overs and give them a complete, non-PR impression of the cultic religion. The BKs are good at PR and bad at covering up what goes on inside. Until we came long, the general impression of the BKs was completely controlled by them and even academics had swallowed the whitewash.
