This day which began in 1970 commemorates the same day in 1920 when women were given the right to vote in the USA.
This is a good reminder that those who say woman have always been equal in the US either don't know anything about history or they hope you don't know anything about history.
It's so interesting when people who say they are against women's rights talk about flipping the situation in a way that implicitly acknowledges the injustices women faced and sometimes still face.
Men who wish for a return to the good old days when women had no legal rights don't want to be treated like that, oh, no. Give them patriarchy or give them death.
