I'm not Catholic lapsed or otherwise but I was a member of a conservative evangelical church for quite a few years.
It's astonishing that anyone can seriously claim that radical feminism is embedded in patriarchal religion.
Traditionally, Christianity has taught the ontological subordination of women to men. In layman's terms, that our nature, our being as women is inferior the nature and being of men. They would quote Bible verses which speak of men being the image of god and women being the image of man.
As a reaction to second wave feminism, churches largely changed their tune on this. They stopped referring to the ontological (innate and essential) superiority of man over woman and instead switched to men and women being equal in essence but unequal in function and role. This is still a popular view in many conservative evangelical churches. They'll say things like ''men and women are equal in the eyes of god, but god made men to lead and women to submit''. I don't know what variation of this is taught in Catholic churches but given they still forbid women from joining the priesthood I would guess that they do teach that women and men have different functions and roles within the 'body of christ'.
This suggestion that rad fems are in some way colluding with patriarchal religions to uphold and strengthen an oppressive system which gives men all the power and all the control is clearly divorced from reality.
