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 1947. Also the reason you might see it on internet and blogs is because of lack of education. Perhaps 30 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
