History of International Men’s Day
In 1968, an American journalist named John P. Harris wrote an editorial highlighting
a lack of balance in the Soviet system, which promoted an International Women’s Day for female workers but failed to deliver a male counterpart. Harris stated that though he agreed there should be a day to celebrate women, the day served as flaw
within the communist system.
Yeahhhhhhhhh, the notion that men need a day to tell them how great they are USED to be called "Super Bowl Sunday", a celebration of masculinity, competition, and friendly rivalry which is a bedrock need for men and has been shown to be true across many generations.
Anyway, sounds like you roll up a lot of internal PR into the DEI banner at your company. Nothing wrong with that, and promoting a culture of tolerance between clashing cultures is fine if that is necessary for your workforce. Its the idea that you MUST have a certain ratio of genders or ethnicities, for no reason other than "equity" as a concept, that is the rub because it undermines meritocracy and proper function of organizations at many levels.
