Then as those roles are indeed slowly being broken down it stands to reason that each successive generation is less willing to put up with them - but if you still see them as normal it will come as a surprise.
Except...entrenched gender roles are normal. This is expected human behaviour for 90% of the world. Equality, be it gender, age, ethnic or religious, is...just not how things work. It may be distasteful for you personally, but the rest of humanity doesn't give a toss - Western civilisation is a thin smear of civility which only popped up in the past couple of hundred years, and what's worked quite well for millennia is what's still working pretty effectively for several billion people.
There is no absolute right and absolute wrong to gender equality, and that there is a regression or progression over time, merely opinions shaped by culture, background and opportunities. The events of the past 10 years have convinced me that the "good" parts of liberalism are unsustainable because people at their core are just...selfish. The only way to convince them to change something is if it is in their self interest. Regrettably, equality rarely aligns with self interest because it requires relinquishing something. Equality and equity of opportunity only exist when the opportunity exist. Otherwise it's back to the dumb old shit we used to do.
Edited to add:
I didn't phrase it well above,
The ground state for humanity is inequality. Whether we wish it or not.
The pursuit of equality and equity means these things need to be prioritised above other things.
It is hard to convince people to prioritise something they are not invested in, especially if they don't benefit from it or value it.
