The pictures depicted above are clearly offensive to hindu people. I am not surprised that he got a threat from extremist people. No mattet who you are or what you do, you always need to consider the feelings of people that are around you.
Nepali people do not have a feeling of preserving their culture and tradition. Pulling yourself out of those practices and doing something derogatory are considered very cool and interesting. Its just a matter of time till we loose our culture and tradition. Half of the youths are slaves on other countries who doesnot even have a clue about the traditions that has been followed by his parents and the other half are either on a line to to fill an application for slavery.
Somebody save my country!!! Sad but true I am not any different from those folks.
