@howdoesatoastermaketoast perhaps if there is this new concept of liking women and transwomen, women who wish to reject Bi as a label need surely to come up with a new word, the equivalent of Pescatarian? There is no legitimate justification for taking the word Lesbian to describe a different concept, and saying that there is now no word to describe the concept of adult human females who are exclusively attracted to other adult human females.
I wasn't saying that such women should never use the Lesbian label. Like, there's no problem with a fish-eater saying "no thanks I am vegetarian" when they are being pressured to eat a steak and they really just fancy a salad, and they can even join the vegetarian society if they want in order to get all the cool recipes and promote vegetarianism generally. But if they use the vegetarian label of themselves in this way it should be done with respect to those whose boundaries are in the more usual places and not campaign for those boundaries to be moved for everyone in order to ensure they don't feel like a second-class vegetarian.
So likewise more "inclusive" women should be clear that they are aware of the difference between themselves and the real deal when it comes to being a lesbian - and if they choose to self-describe as lesbian whilst being open to male partners should make it clear that this is an exception, not a rule.
There's no judgement to someone saying "I am basically vegetarian, but I make an exception when it comes to Mussels because they are just so delicious and they don't even have a face so let's just call them honorary mushrooms"
Likewise there's no judgement if someone says "I am basically lesbian but I make an exception for males that immitate femininity really really well"
And if you're not currently being offered mussels/helping to decide the menu at a veggie restaurant (and if you are in a group of other women and not currently helping to decide the rules for a women-only service) then you probably don't even need to make this clarification, you can just be one of the gang. You only need to care about the difference when it's actually relevant.
