ZHIGRANA [ "A" Certificate Movie - Scene Removed by Nepal Censor Board] WHY???

OUR MOVIE WAS GIVEN AN "A" CERTIFICATE WHICH ARE ONLY MEANT FOR ADULTS ABOVE 18 YEARS OF AGE. The international definition of A certificate movie is : Only for adult audiences (18 years or over). Nobody below the age of 18 may buy/rent an A-rated DVD, VHS, UMD or watch a film in the cinema with this rating. Films under this category may contain adult/disturbing themes, frequent crude language, brutal violence with blood and gore, strong sex scenes and/or scenes of drug abuse which is considered unsuitable for minors. We were given an "A" (Adult) Certificate and were told to cut this intimate scene amongst others. Is it Fair??
