Yet TOS was nothing but sexism which then made sexism a reoccuring theme in Star Trek haha.
I would be inclined to disagree. We may not think much of it in the 2010's, but in the 1960's it did make several strides forward in that regard. While shooting itself in the foot repeatedly, however.
Reminds me of a quote from a player in the North American women's gridiron football league, which puts their players in rather revealing and suggestive uniforms: "I don't care what they put us in, I'm just grateful for the opportunity to play." It's a step, that's better than nothing, and sort of in the right direction.
