I tend to find that those on the BA board fly BA much more than BD board posters fly on BD, that however is not always the case as there are certain posters who seemingly never or rarely fly BA at all, yet seem to have opinions on almost every thread and inevitably do in fact take an apologist tone and defend almost everything about BA.
Regarding the "in" crown and all of that, while I do think it exists to an extent, it is not hard and fast. I have rarely gone with "the flow" of the BA board, yet have been an active member over there for over a decade, so it really does have to do with your character and how you post, not necessarily the position(s) you take.
