Buddhism is quite possibly the most dogmatic religion in the world, by which I mean its doctrine is highly detailed, explicit, and systematic in a way that makes Christian scholasticism look downright sloppy.
But then there's business-exec "Zen" which I guess entails sitting in lotus position while thinking up new paths toward productivity, profit, etc.
Could you expand on this and give some examples, please? Your idea is intriguing, but I would like to understand what you mean more clearly.
I'm assuming you're asking about the "scholastic" aspect of Buddhism. Starting with the sutras, Buddhist teaching tends to be presented is a very schematic fashion, e.g. the Four Noble Truths, the five skandhas, the six realms of samsara, etc. Some Western Buddhists have tried to frame the Buddha's teaching on karma and rebirth as either a) mere metaphor or b) superfluous cultural baggage, but this is quickly dispelled by a cursory reading of the sutras where an incredibly detailed and systematic description of different kinds of karma and resultant rebirth is laid out. The presentations of this sort are often exhaustive to a point of tedium, though the "hell realms" and "hungry ghosts" can make for fun reading. Likewise one will find systematic presentations of mental states, objects of contemplation, etc. Buddhist doctrine was further systematized with the Abhidharma literature. These tendencies carried over to Tibet, China, Japan, etc. who developed their own scholastic systems such as the Tibetan lam-rim.
This picture doesn't gel well with the perception of Buddhism as a non-dogmatic freethinkers religion. That perception came out of a lot of Buddhist, especially Chan/Zen, literature being presented in the West out of context. For example, when Zen masters urge their disciples to abandon the scriptures, they are speaking to a society where the Buddhist scriptures have been widely studied/ disseminated and the basic doctrines are widely understood. And in fact all the teachings considered unique to Zen are traceable to scriptures and schools of thought originating in India and make a lot more sense to someone familiar with those origins. But Western "Zen" practitioners took the "outside the scriptures" quotes as a license to fabricate what is essentially a ritualized self-help philosophy.
Western Buddhists though who are looking for more genuine Buddhism will find it more likely in the fairly uncompromising Tibetan and Chinese centers where the scholastic and liturgical qualities tend to remain intact.
