about people not paying attention to WHY they have the beliefs they do in the first place. A lot of people tend to live their lives with opinions based not on anything they logically deduced (tee hee) themselves, but based on social mores that weren't mandated by a god or religion, but by some man (well, in the case of the emperors you cited, i guess you could say that they were both, in their opinions).
point is, many of the ideas about what is "right", "good", or "moral" in society have shifted throughout the millenia. So to be so rigid in what one thinks without examining the why seems pretty durned illogical, if not downright stupid. I'm not saying i wholeheartedly agree with you, mm, but it's something that we should remember to keep the conversation in context. 50 years from now, it could be the norm for women to have kids without men and raise them by themselves. Hell, 50 years from now, it could be the norm for it to be the other way around! Such is the nature of humanity.
