OP:
For the most part, you can still do those mitzvos even without being chayev in them. You worded it as if you have a kasheh on the halachah, but if you think more about it, your problem might be with socio-cultural norms that prevent women from doing these mitzvos.
UJM:
“primarily due to the negative influences on the world (over the last 100 or so years) from the terrible feminist/women’s liberation movement. It affects people without realizing it, even those who think they’ve been immune to it.”
Yes, but this goes both ways. The Mishnah Berurah says we should be choshesh for the Ramban and have women daven shachris and mincha, yet now it’s stigmatized more due to overreaction to feminism.
