While any religion has to be a control mechanism to a degree (its inevitable for any set of teachings and behavioural instructions, and there are all that, near-definitionally), not all are as politically and economically charged as the abrahamic religions, no. They in particular, however, are spiritual and belief systems woven into political and financial systems that lead to the dominion of the central religious authority over the people. Not true of, say, buddhism, obviously.
Deism is pretty obviously not a religion at all. Confucianism is more of a religion. Both being philosophical positions, and the latter being instructive on behaviour, the former not, even if desim is the one that has *something* to say about the nature of the universe and out place in it (made by cosmic engineer, we dont really matter) while confucianism is agnostic/apatheistic. Hell, marxism and keynsianism are more religious than deism.
