It’s not “insignificant” or “silly”. If someone feels that someone or something is prejudice against them because of their gender, race, orientation, etc, then it shouldn’t be thought of as “silly”. To that person, or people, it is significant. I understand that “man” can be used to mean mankind, however since this award is recognizing one individual or person, it seems more appropriate to make a simple change to “Person”. Also, you used the male pronoun “he” in the format for nomination instead of a neutral pronoun or “he/she”. Even Time magazine, who used to have a Man of the Year award changed it to Person of the Year, because of the issue of sexism. So, I, among others, still believe this should be changed.
