I was around for the tail end of 2nd Wave feminism, and I would say that it was far from dehumanizing or reductive.

I don't think younger people understand what women were up against. We were not considered deserving of basic human and civil rights. In the US, to this day, women do not have an Equal Rights Amendment.

2nd Wave feminism, as I remember it, was a broad movement composed of women, normal women of all colors, who were fed the fuck up with our oppression. There were radicals, and that's what killed it, but so much of it was women, just average women, in a collective roar.
