There are plenty of problems that are unique to men, whether that fits your narrative or not. Vastly higher suicide rates, vastly higher workplace deaths, widespread infant male genital mutilation even in developed countries, selective service, court bias (criminal, divorce, and custody), lower life expectancy, vastly higher war casualty rates. Is it really that upsetting to you for these issues to take the spotlight in the context of masculinity for one day a year?

By the way, most of those groups you listed already have awareness days.
