1) Why do younger people gravitate away from 'modesty'? Easy to answer. 2) Why do most ancient traditions and many old people encourage modesty? If you don't know the answer to both questions, or at least respect both sides, you are not qualified to comment. It's fine to be modest, it's also fine to run around. If you say that only one of the two is okay, as most commentators say, then it means you don't understand the other. If a person asks "Is beer or wine better?" and you say "beer of course" and they ask "why not wine?" and you say "I have never tasted wine" then you are a moron.
