"Being able to express happiness and their love for that matter relates to normal human engagement of people being able to talk to each other and express opinions, not necessarily publishing" : Let's talk about the majority. Majority of women, if they want to get rid of the expectations and gender role projected on them, if they want to escape doing all the household and child and elderly care "duties" by themselves, and want to enjoy at least part of the "blissful dreamy domestic life with support and happiness", they do have to point out things like they are humans too, with wants and choices, and that is feminism. And, if we talk about the minority rich women, well if they are crooked or not self-respecting enough, they can get away with emasculating their men, saying they are not man enough if they want their wives to perform any domestic or care "duties" by themselves, those men control almost all the money and power in the world, so these women don't necessarily have to take help of the idea of feminism to get the domestic bliss they want. But, if they are dignified enough, they would stop using dirty tricks like the above, and talk the language of feminism to get the life they want.
"And women in affluent families enjoyed intersectional privileges over men in the lower strata and on the streets in the past. How could women protest in the first place? How could women influence the men in their lives to bring about positive changes?" : This is true, and nowhere I am trying to the argument to men vs women. So, what is it that you are trying to say? Women (and men) from affluent families always have privileges than men (and women) from poor families don't. And this is why "white feminism" is so ridiculous and harmful to most women (because most women are not from affluent families) and this is why affluent men showing affluent women how majority of the women (lower class) suffer and still don't shout patriarchy (actually, we do, these men just don't care to hear those) and do hard work and conform to the gender roles is so ridiculous and audacious. I just wonder why the women around them don't reply to these by showing them how hard the lower class men work too, compared to these privileged men, but I can understand why most won't, because capitalism and patriarchy go hand in hand, so it's much easier to tolerate some nonsensical insult than showing the hypocrisy and getting pushed away from the pinnacle of the pyramid. This is why there's a much more sensible concept called "Intersectional Feminism".
"I hope you would not say feminism allowed women to walk and talk, that is too much of a stretch.." : What is your idea of feminism, really? For me, going against the status quo, gender roles and expectations, and asking for choice, equity and equal opportunity is feminism. And, women's gender role in the society mostly is being obedient, docile, adjust to the man, to his family and to the expectation of the powerful people from politics, religion, business, government,.... And, women defying these expectations and demanding their rights to choose their own lives is feminism to me.
