Why in the fuck are non-lesbians such a protected group in lesbian spaces???

Well, a lot of communities discourage or ban discrimination against demographic groups that do not necessarily include lesbian women in their ranks-- e.g. gay men and bisexual people in this sub, or groups where some people are lesbian but not all-- for example, discrimination on the basis of racism/anti-semitism. (edited for clarity)

Personally, I hate lesbian spaces that are biphobic. I left s/lesbians in part because it used to be very biphobic and I was sick of it. Why is there a need for such negativity? Sure, if people have actual stories they need to rant about, they should, but more often what happened was people would just start making baseless generalizations about all bisexuals being "manipulative" or some shit, that's total bullshit.

All I said was there is animosity between lesbians and bi women, typically because we have to share spaces with male-partnered women who get upset because we don't like dick/men.

Yeah, I mean I don't know the sub/context but it seems ridiculous that you were banned for that. You could talk about this more in the "Censorship Thursday" post in a couple of days.

I swear I get banned more for biphobia than anything else in lesbian spaces. Even though most of my exes are bi women or lesbians who fucked men before.

You could still make comments that are individually biphobic.

Why are goldstar, man-hating lesbians like me public enemy #1?

I don't know about being "gold star," but acting like a "man-hating lesbian" promotes a homophobic stereotype about lesbian women. I have lots of male friends and I don't know why the hell people think this is a thing, lol.

Does anyone track the sexuality of mods? Are all mods bi??

All mods, ever...? No. But on Reddit, a highly disproportionate number of mods are transwomen, and on average they are extremely easily offended.
