You point out something interesting. Even though the BKs have their own discussion forum now, it appears few BKs actually gravitate towards it and it's helluva dry reading. Little of interest to engage with, no controversies, no newcomers or outsiders at all.
Instead, as you say, they are swamping on Facebook ... but do they actually have conversations or just go "Wah, Baba!" and post pictures of Dadi Gulzar and baby Krishna?
This surprises me because if reading newspapers and watching movies are consider "Maya" by the great god of the BKs in the old days ... wasting time on Facebook ought karmically condemn any BK for eternity. Pushing electrons around the internet just ain't good karma, nor old fashioned service.
Surely it's a huge waste of Confluence Age from a BK point of view?
Personally, I find the internet or IT brings out the very worst in autistic, dogmatic BKs (no offence to anyone suffering from genuine autism), and even real live BKs have said the same to me. BK and nerd just don't go together well. It's pointless to argue with them because they don't operate on a level of logic ... the worst I have read are literally turning concepts such as logic and objectivity upside down. I think you're wasting your time trying to appeal to them on that level.
Few BKs have an operational intellect and even less have intellectual integrity. Please correct me if I am wrong. BKism is about 'acceptance through repetition', and warping the meaning of existing words and concepts, not any true understanding. Adherents are reward for new advertising strategies and unquestioning conformity, not genuine insights.
If you want some real fun, go challenge the BKs on the BKWSU Wikipedia page. They are very sensitive about it. BKism is just all about thought and media control and the only way you'll really get their attention is to challenge them where it bothers them.
Facebook is a waste of time because whatever you write just disappears in days but Wikipedia they really care about.
The BKs have been fighting for years to gain control of the Wikipedia BKWSU page and turn it into an advert for their religion. Recently a coordinated team of them managed to have me banned yet again. I mean, they spent about 95% of their time twisting facts and snitching, and putting in Admin complaints against me until finally they lucked out. Now they have turned the topic page into all the usual garbage, half-truth and lies you'd expect from the BKs.
"Blah, blah, blah ... the United Nations" etc. It's bullsh**.
They've even reverted it to factually erroneous lies and cover ups. Factually erroneous lies even their leadership and IT coordinators know absolutely are lies ... like Lekhraj Kirpalani being 60 years old in 1936.
Brahma Kumari adherents have no conscious or morality, it's just all about expediency and if lying and fabricating, and snitching gets them what they want ... they'll do that.
If you really want fun interacting with BKs, it's the place to do it.
