You may mistake here, rushing to the other extreme. Anyway we should avoid jumping into easy and fast conclusions. Your desire to discover the facts is great, but this may misguide you into speculations.I am thinking that the entirely portrayal of the early days by the BKWSU is false. Even down to the casting of the Bhaibund as the "Anti-Party". For me, the Anti-Party is within the ranks of the BKWSU and runs the show now. The Bhaibund were acting to their best abilities out of genuine and reasonable concern.
What we know is there has been some change in Brahma Baba and from having gurus he had become a guru himself. There are many evidences about the "purity" matter, it has not been simply for spoilt children. The purity matter has also been introduced little bit later, and the process of purification is indeed through remembrance, but remembrance is there only when there is practical experience and influence. During the golden days with Brahma Baba, when people used to have experiences with him, lived with him etc, for them Yaad seemed to be something very natural and easy and just his company has been a guarantee for all attainments. The idea about the Supreme Soul like a point of light has been developed later by Mama.
The court procedure also has contained these purity matters and has turned into manifestation of woman's rights. This same purity matter is bringing problems till present.
Surely Om mandli must have also played its social role, through becoming some local authority in competition to the traditional moral and jurisdiction, but having in mind the revolutionary potential it is believed for this gathering to possess, opposition has always been expected. This gathering has started to rearrange lives of people, so reaction to it will be there. I don't know how it is with other cults, but by putting the BKs in the same list i think you diminish the self importance they attach to themselves. There is the ambition for world sovereignity, they speak of highest on high God etc. so if you say that everything is simply to earn the bread, you diminish their crime, if you think there is such.
