I think this chapter's message is the best we could get for this year.
What I am surprised is that she actually called herself a lesbian. Big shock, I know. By that I mean that, Japanese people don't use the word "lesbian" as over there it is synonymous of Porn.
I think you misunderstand how translation works.

probably the original jp had レズ ("Les"), which is pretty commonly used to refer to and self-identify as lesbian in a non-offensive way.
Oh? I thought "bian" (ビアン) was the more common term for self-identifying, partly because レズ was so often used in a derogatory manner. (At least, I'm pretty sure I read that in some older stories around here, but times could be changing.)
Yeah, it's basically moving in circles. In 90s and early 00s, Les was sometimes used as derogatory as well, so some people started preferring Bian. Those connotations are mostly forgotten by now, though, and many new people just use Les - in my opinion also simply because it's easier to understand for people outside of the community
