"Also, there were probably those who considered that preventing women from getting college degrees was part of the "culture" back then, and that giving women the same oportunities as men would be an example of "cultural collapse"."

Not an example, a necessary causal factor. Women destroy every institution they enter, so it should come as no surprise that their involvement outside the family is a good metric for cultural collapse.

I was laughing at the GoodReads winners selections. You only had to look at the covers to see that women voted for them. And still people wonder why so much literature is shit and book sales are in decline.
