Will read the links but have to ask why waste the time trying to change her? We get super set in our ways as we get older and hold to what we believe tighter, because most of what we are is done.
Save the little time you may have with her reflecting on postive stuff.
Will save you a lot of headaches, my moms the same age and she has totally neive understanding of the world and if I pressed lately it would turn to tears. They are a lot more fragile in mind at this point then you may think. Funny you went through all that feminism garbage like me, but now my mom denies she tried to instill it. Could easily go to her bookshelf and point to the books but lifes to short.
We all have our faults, try to except them. She is not changing you any more so why fight!
Will come back tomorrow after checking the links.
