Fair enough. Gotta admit, my Space Marine Chapter knows so much especially about the nature of Chaos, if many Inquisitors knew about it they'd declare them Heretics, hunt them down & try to wipe them out.
Of course, they'd have to discover my Chapter exists in the first place...
Plus Ynyr Kage, my own Inquisitor, got into the Inquisition through a...back door...
So I guess I'm not so "Puritan" myself. Never claimed to be though...
