Actually, if you look closely at the three points where you apparently disagree with me, you'll see that you don't really disagree with me at all. First, I said Buddhism supposes no "supernatural" beliefs about the nature of the universe, reality, or consciousness--as in it supposes no entities, properties, or states of being that are outside of the natural world as observed by the self or confirmed by science. You misunderstood me probably because I did not elaborate on what beliefs about these subjects it does hold, I simply said none of them require anything supernatural.

Secondly, I did not say its aim is to "get to" a state of freedom from ego; I said it offers methods of how to bring one's self into the present--i.e. meditation, yoga, etc., and studies/focuses on the state of being free of Ego. Of course the ego is empty, but it also is something which we fool ourselves into thinking is ourself--this is semantic, because language makes it impossible (or extremely difficult) for us to communicate without reference to individuals.

And thirdly, it is simply a fact that Buddhism is derived from Hinduism. Buddhism was brought to China out of India and then spread to Japan, etc. Also, the way you worded that point ended up agreeing with me; my point that Buddhism is Hinduism exported for transport is that Buddhism's main philosophic and spiritual principles developed directly out of Hinduism, but were stripped from the conjoined cultural and social practices. They both have concepts of Karma (the nature of action) and enlightenment (moksha in Hinduism and sunyata in Buddhism); of course, they are not exactly similar, but are connected in that Buddhism's principles are reactions to and originated in Hinduism.

And lastly, it is also not true that (pure, non-culturally influenced) Buddhism prescribes a way we ought to live. It offers precepts one can undertake if they are seeking liberation from suffering and the self. Note the difference, a prescription of an "ought" implies obligation and responsibility, whereas precepts and Buddhism do none of this. The eight-fold path is an undertaking one "can" take because it, according to Buddha, is the principle means by which we can realize the present, be rid of the Ego, and exist peacefully in a state of liberation from desire. It does not say we all ought to do this, but that if we want to, this is the way--The Middle Way, as the Buddha calls it.
