Take Ellen Ripley for example: strong woman. Can’t be played by a man as the character no longer makes sense.
Ripley was originally not even written as a woman.
There is not a single scene in the original Alien where her being a woman is in any way relevant.
Communism is a society without social classes, money, or a state.
Feel free to name one so-called communist country that implemented that.
The eastern block was as communist as North Korea is democratic.
They did however socialize ownership of factories etc, so they did have an authoritarian form of socialism.
