You missed the point of my post... The point has nothing to do with whether Indian culture exists.. The point was that there isn't just one 'Indian culture' and that your version isn't better than mine. Like you mentioned.. there is no way to compare cultures. We both are saying the same thing.
My family may believe that eating meat is ok, someone else may believe you should be vegetarian. One may believe that enlightment can only be found by accepting the word of God, Someone else might believe that you should find your own way to enlightment.
By the way.. showing your underwear isn't part of the general American culture... just because a few ppl do it. Drugs as well... if that's your case, then people in India have been doing drugs long before America existed. There is a family value system in America... strong family value system.. do some research on that.
