There have been previous waves of feminism throughout history, most of these waves achieved some temporary level of success before their civilization collapsed as a result of being weakened by women getting out of line, leading to its inevitable replacement by a more patriarchal civilization. Hence, you were either patriarchal in history, or you were simply wiped out or enslaved, and this is why there has never been a matriarchal civilization. Our current waves of feminism have been the most successful ever because technology has enabled this to go on far longer than it should have. There is now a huge technological gap between first world nations, and third world countries, unlike the days of Rome where a bunch of barbarians could sack a superpower.
But all this gap does is buy time, nothing more. The West is declining as we speak, a process which is hastening, and it will inevitably collapse and be conquered by a more patriarchal civilization. Once that happens, all Western culture will be erased for good, and women's rights will be set back another thousand years, with the cycle of history progressing on.
