This kind of reasoning perpetuates the patriarchy. The patriarchy IS disadvantaging women. You can't just wibble on about how it's not sexism because it suits you, when it blatantly is sexism anyway. There are so many negative connotations to men taking their wives name and to "difficult" women who don't conform.
Just because you make an anti-feminist choice it isn't your fault, you don't have to excuse it. Half the problem with living in a patriarchy is that women blame other women, or themselves. Blame men instead.
IF MEN WANTED THINGS TO BE DIFFERENT, THERE WOULD HAVE BEEN CHANGE BY NOW
Our societical structures are deeply entrenched. Its often just easier to go along with the status quo. Those in power put in place structures that benefit them and that support their continued supremacy.
It's like the women "empowered" to take their clothes off for money or do other sex work "because they want to". Yes it's their choice but it's still a damaging norm that a woman's body is a commodity and certain men view women firstly as sex objects. This attitude can lead to sexual violence against women and girls, but it's not the stripper's fault.
Or the women taking a backseat on their careers "because they want to". I'm sure they do want to but it's still the women who mainly give up on careers and its still more men in senior positions. This leads to women being economically disadvantaged as a sex, and makes it harder for women to get into more senior roles. It's still not the fault of the woman making her career choice.
Just call a spade a spade, and a patriarchy a patriarchy. Taking your husbands name is inherently androcentric and its nonsense to pretend otherwise because of your own personal circumstances.
