To me a lesbian or female-leaning bisexual is someone who centers women in her life, NOT men. Unfortunately, it seems that the popular conception of this is that this must mean you center your attraction for women, rather than women themselves. It's like a male gaze oriented view of your relationship with women rather than a female gaze oriented relationship with women.

When a woman takes a male gazed view by centering their attraction towards women, they tend to treat the women in their lives as objects of consumption. They find more fulfillment in viewing women sexually or as objects to be acted upon.

However, when a woman takes a female gazed view, they center the women themselves. They find fulfillment in uplifting women and take pride in seeing them act for themselves. This does not mean that she never views women sexually or never wants to do things to them, but it just tends to be secondary (though still enjoyable) and not the sole focus of the way she values women. Her hobbies and media consumption more often features female leads and artists, though not necessarily exclusively, particularly depending on how niche her interests and values are. If a television show or book series for example does focus on males though, they tend to exemplify "female values" so to speak, and even masculine warrior type males will demonstrate nurturing, supportive, and community-oriented behaviors and relationships. Think Luke Skywalker and Eragon.

Above these points though, a truly lesbian or female-leaning bisexual woman does not center men. That means she is not constantly complaining about men, bemoaning the patriarchy, or talking scathingly of heterosexual relationships. Of course she is going to be aware of the issues surrounded toxic masculinity, patriarchal values, and heteronormativity-- as well as the unique ways these affect our lives as lesbians and those lives of bisexual women. She will likely be engaged with current events and social issues, and be able to converse critically on them. She may even be a feminist activist or a radfem. However her daily conversation will not be constantly filled with criticisms and snarky asides of men, because lesbians and female-leaning bisexuals have lives, hobbies, interests, and daily activities that have nothing to do with men and which they would much rather talk about and enagage with.
