The attributes of western humor shouldn't be expected in an eastern society and especially among political dignities. Each culture has its own ways of expression and celebration. There always exist a difference between two cultures. And that difference is essential for the survival of those cultures independently. Mixing of attributions from 2 cultures will always eventually result in fading away the values of the weaker one. And you don't at all want to see that happening.
In political world a politician needs to very much careful about his social life. And when it comes to the combo of Islamic country and eastern culture ,we make it more tougher on them. They will pay the price for even their very self related actions. For instance, Imran being such a great human paid a huge price for marrying Jemima Khan. A patriotic person like him had to prove himself a true Pakistani not someone from a Jewish lobby. Don't we know how patriotic and nation lover Imran is? Yet, in eastern political world being a leader you have to make social decisions considering the sentiments of the people.
Another recent incident happened in Salta Argentina, when few hockey players were fined for taking pictures with some girls.
Do we think in today world Imran or hockey players should have paid the price for their actions? Most of us will positively say NO. However, they had to because of the cultural boundaries we are surrounded around.
Personally, I think there should always exist such boundaries. Such boundaries don't necessarily make us " Paindos" but it helps us in retaining the values of our culture. If some values in a culture start losing respect, eventually through evolution you end up losing those values and culture and history is full of such examples.
So lets not expect our leaders to learn the humor of dancing :)
