Literally the only place I have seen international men's or women's day mentioned.

Really? Usually I hear a lot about Women's day, and it's not uncommon for women to get candy and a nice letter from people. It's less common for men to receive it, but I know some people who received it.

Every year they complain about international women's day and there will he a front page post that boils down to "happy international women's day now go make me a sandwhich" And then today when those exact same people have multiple posts on the front page talking about how it's fucked up nobody celebrates international men's day.

These people love to complain, but do nothing to help other men.
