Atul Subhash laid down his life to raise awareness on persecution of male gender in India through one sided gender biased law. He exposed the corruption in judicial system and how the Indian govt. and judicial system is harassing the men and their families including sisters and mothers of husbands. This event should be known worldwide. There is a wikipedia page for it: https://en.wikipedia.org/wiki/Suicide_of_Atul_Subhash

Hence, a stamp to commemorate 9th December as Atul Subhash Day would be very appropriate.
