Women with "traditional values" have always felt it was not in women's best interest to pursue equality with men especially in the dating and sexual arena of life. They loved chivalry.
Progressive women oftentimes view chivalry as sexism.
They resent being seen as "the weaker sex" and instead want to be able to have the same opportunities/choices as men in society.
What makes a "double standard" in part is when (both genders) agree something is wrong when one of them behaves a certain way.
If for instance no women looked down upon other women who had multiple sex partners women would be on par with men who for the most part don't put down men for doing the same thing.
Where as many men might admire a "playboy" who has sex with many beautiful women a "traditional woman" feels threatened by women who dress provocatively and are sexually liberated. They believe these women make it that much harder for them to find and keep a "good man" or at the very least affect how men view women.
I believe what's stupid is caring how others choose to live.
Life is a (personal) journey!
