Dione Nothing in your post would be incompatible with an 80s definition of Liberal Feminism.
Which I'm finding quite interesting. I'm wondering if, in fact, there is only Liberal Feminism (by its 80s definition), these days?
Perhaps it's a question of comparison. In the 80s, Women's Aid would be seen as Liberal Feminism in that it worked with the existing system to reduce the harmful effects on women of that system and to create choices (leaving abusive men) within that system. women involved with Women's Aid called on the existing system to recognise an injustice and to change legislation that kept women with abusive men and failed to recognise harm to women within relationships. With some real success (thank goodness). Changes to police procedure and recognition of rape within marriage are real landmarks - even if we still have much, much further to go.
However, this took place within a feminist terrain where women were actively critiquing and setting up ways of living outside of heterosexual couple relationships and argued that anything less was simply shoring up a deeply flawed system. How many all-women communes still exist? Do women still become lesbians for consciously political reasons? Those experiments have kind of had their day (for many, varied, and interesting, reasons).
Perhaps 'Liberal Feminism' is something whose definition changes in relation to its 'other'? And the 'Other' - and consequently 'Liberal Feminism' - just isn't the same thing in 2018.
