There are zero positives to feminism, and the things you mentioned didn't require feminism to happen.
Oh, I get the point you're making now. I agree with you that I said the same thing in a roundabout way (hence, the Charles Manson reference.)
Without saying feminism is a positive, I would say it sort of filled a power vacuum at least. American society in particular was/is fragmented ("the melting pot"), materialistic, puritanical and sexually repressed which led to weak, insecure men who welcomed "strong" women who were more sexually available. Feminism exists because of weak men both individually and also collectively (the conservative ideology rejection of "identity politics")
