I'm not protecting it on your behalf. As we know you like to redefine words as and when it suits, which is what you're doing here.
Lesbians are same sex attracted biological women. Unfortunately it's necessary to put biological in there for clarity because people like you have redefined the actual word 'women'. Two transwomen aren't lesbians because by definition they aren't same sex attracted women.
Thanks for telling me what lesbians are. Honestly I was clueless before. (that's sarcasm just to help out the stupid).
If somebody is male and says they are a lesbian, they haven't taken away my self-knowledge. If I choose to sleep with a male who says he is a lesbian with an organic strap on - I will. Honestly I really don't need your help.
Oh and by the way, I haven't redefined the word woman. No woman has had her gender identity erased by anybody else. And why are you so protective of other women's gender identity, when you don't know what one is?
I could invent some new words if I put my mind to it though. Oh here's one ... 'cockwomble' ... someone who is always wombling on about other people's cocks.
How about 'evangenital christians' ... a bit more self-explanatory that one.
