Do certain principles of Buddhism disturb you?

Some principles of traditional Buddhism have disturbed me in the past, that’s for sure. Certainly rebirth is one subject that is always a thorn in my paw. I have tried to wriggle and wrangle that issue to conform to my understanding of a material universe without supernatural forces, so as to unify the principles of Buddhism that I embrace with those that seem arcane and superstitious. Now I realize that the fundamental point is that letting go of these differences is the important step in going further towards enlightenment. Do you enjoy the thought of “literal rebirth”? Well then go ahead, and believe in it, I surely don’t care if it contributes to your happiness. I certainly would never start an arguement about it, that’s for sure.
