No, it's not because the opposition was convinced they are wrong.
The change was simple: the opposition died out.
Over the years, I've heard and read many and many opinions about various discrimination policies, male privilege, and whatnot. And, what stays as a common element to every "feminist" writing is how we, the males, need to change somehow. Some were the ravings of a mad man, I am sorry, woman. Some were practical, sensible, rational, judicious and so on. However, well, they fall to deaf ears.
All that can be done about the issues we have in our current society is to teach our kids to not fall prey to the same mistakes we are doing.
If the father is sensible, he'd probably try teaching such and such obvious truths to his kids no matter what some woman he has no relation to is shouting on the media.
And, hey, if a given male is a chauvinistic pig that needs reprogramming as far as the feminists are concerned, then probably it's his WIFE that will do all the teaching and raising of their kids. Heck, this is one of the issues feminists have, after all, an issue that will probably die out the hardest. So, why the hell is anybody trying to put anything at all in said chauvinistic pigs' heads? It's their fucking wives that need to learn.
Leave us males alone, the feminists need to concentrate on teaching the female half of the population how to behave.
P.S. no, I know this is not feasible. I am just simplifying everything for the sake of narrative structure. It's the kids that need to be taught, from the get-go. Still, I don't think I am mistaken that it's a better idea to try to reeducate the women than to try to reeducate the men.
We need to wait for the current generation of feminists to die out before we start noticing any changes to the situation.
Have fun with that.
