I cannot believe that 395 replies later we are still discussing womens rights in TOS. Yes it was sexist, yes women wore revealing clothes and impossibly short (and very impractical) minidress uniforms. No it never showed women in command.
But so what?
It is a product of its time and should not be judged by our modern sensibilities.
You either accept it as such and get on with your life or you decide it offends you and go watch something else.
Simple!
Are you new to Star Trek fandom?
