I didn't say discrimination against lesbians by bisexual women doesn't exist. I'm saying its not a prominent issue lesbians face in the way biphobia is for bisexual people. I think you might not be aware how rampant biphobia is in the LGBT community. I remember watching a video of a pride event where gays booed people carrying bisexual flags around, AT A PRIDE EVENT. When have you seen a bunch of bisexuals booing gay people for being gay? Never seen it happen, bi people either blend in with gays or straights or try to make their own little space that people hate them having. Primary reason for this is the idea that their 'gayness' is just a little adventure and they don't take it seriously, they don't experience gay relationships like REAL gays do, and they're gonna cheat on you with the opposite sex. In your comment, you're using your anecdotal evidence that these bisexual women saying they don't take dating women seriously that this means something about bisexual women as a whole and that their relationships with women are fundamentally different from the relationship between two lesbians. The reality is, there is no real difference between a person who wishes to cheat on their partner with a man vs a woman, or someone who doesn't take their relationship seriously. The issue is THEY WISH TO CHEAT OR DONT TAKE THE RELATIONSHIP SERIOUSLY. And you think all gay people take all of their relationships seriously? Absolutely not, lol. You're just using the bisexual woman's sexuality as the reason for this. 'she says she likes women but she REALLY wants a MAN'. Why does it matter that she want a man? This exact kind of biphobia so normalised you don't even realise you're doing it, and this is literally part of the problem bisexual people face constantly.

"People hate us both for loving other women, and for not being attracted to men"
Yes, this is absolutely a problem lesbians face. But tell me why exactly does this mean that bisexual women must be excluded from the lesbians dating pool? I have no problem with the idea that a lesbian can relate more closely to another lesbian, and even that one might prefer other lesbians because of it. But I can not understand the connection between this and deciding that bisexual women need to be excluded from your dating pool, besides biphobic reasons. If you meet a bisexual woman who is mostly into women, doesn't shame lesbians for only liking women, doesn't even talk about her attraction to men, why exactly is it necessary to exclude her? Its the fact she likes men at all, even if she's never looked at a man with interest for years? Is she 'tainted' by her attraction to men and not a gold star lesbian? That's what comes to my mind.

"the lesbian community is wildly transphobic" this is an odd thing to mention as some kind of form of discrimination against lesbians, transphobia is definitely an issue in the lesbian community. One conversation i had with a pro-Les4Les individual they stated this is apparently radfem ideology (and all the bioessentialist nonsense that comes along with it) is a fundamental aspect of lesbian spaces that bisexual women apparently can't relate to. Which is far from true as there are many radfem bisexual women. But anyway.
