I'd be happy to, but hopefully this will end the discourse, since we've now moved off topic.

I prefer to use legitimate definitions when making sweeping statements about the definitions of others sexuality, so I've chosen to use the Oxford Dictionary definition:
a homosexual woman.

Now, I like to do my due diligence, so let's check out the definition of homosexual:
(of a person) sexually attracted to people of one’s own sex.

But that's tricky, because sex and gender are not necessarily the same thing, and while the OED has a whole discussion on the difference between sex and gender, I think this discussion is off-topic enough. While I'd be thrilled to engage with you further about what "makes" someone a lesbian, this is neither the time nor place to do so.
