He never humiliated his own language and culture by appreciating the others.
-> But in Nepal, ethnic communities have gone even beyond that. Many ethnic communities have lost their language and many have stopped passing it to younger generations. Yet, they're discriminated for being from ethnic communities. 

Danny is awesome and his love for nepal and nepali seem to be unconditional. But I feel sad that I am not aware of him being appreciated in any functions in Nepal.  People from many ethnic community have contributed to nepali literature.

Please understand that speaking and preserving one's culture doesn't mean humiliating other's culture.
