Note that I only used homosexuality as an example of how eastern perceptions of sexuality are different from ours. Sexuality in general is natural, so I don't see any "naturalistic" justifications for prohibiting nudity. Disgust at nudity is a result of 2000 years of repressing sexuality (you don't see that in tribes which go around naked all the time). Because of that, nudity and sexuality are very emotionally loaded and produce extreme reactions. In ancient times (before Christianity), nudity was much less of a deal.
You know, even if that historical assessment was correct (which I doubt), that would probably rank as one of the not-so-bad developments coming out of Christianity. You want people go around you naked? Hell I know I don't. I really like the fact we tabooed that behavior, for all the higyenic, aesthetic, olfactive, etc. reasons. You want to behave like an amazonian? Go ahead and behave so
there. Ok?
Please elaborate on the nihilism part, I'm not sure what you meant by that.
Liberalism has in itself the seed of chaos, for its call for tolerance, equality and cultural understanding (through relativism and so on) are nice concepts but if taken to the extreme they are always self-defeating. So, in this sense, many liberal developments in our culture have created a conservative culture that fights it, because it fears that liberalism will end with the culture we have labored for so long in building, and in exchange it only promises "freedom". This is a very common theme in thoughts by Strauss, the neo-conservatives, etc., etc.
It was even acknowledged and foretold by Nietzsche.
I'm not advocating ditching nudity taboo because I like to look at nude people, but because it's illogical. A pretty girl has just as much right to undress as an ugly old man. You might not want to look at the latter, but aesthetics have little to do with morality. There's nothing immoral about nudity, of any age, gender or body type.
What has logic to do with any of this? Logic is the rules we use getting from one proposition to other propositions. Declaring nudity a taboo is as logical as anything else, given you accept the premises from which this conclusion was derived. To me, the mere objections I have against "nudity" in general are perfectly reasonable premises I have, and using
Logic, I can conclude that it is a good idea to taboo nudity. Period.
