dear being an ethnic pashtun myself the word is highly derogatory the reason why it may not be so in india is because the pashtuns and indians have not come into contact on a large scale and perhaps even more after also the reason you might see it on internet and blogs is because of lack of education perhaps years ago you would hear the n word being used like this also but later it grew out of vogue and politically incorrect similarly i provided an academic reference clearly stating that we pashtuns find it derogatory hope can respect this sentiment best wishes and regards
