The dumb thing is we actually have a word for this.

The word is queer. I'm still unsure as to why this word isn't used for most contexts where the LGBT[...] are currently used. We use the word "gay" and that used to be an insult like "queer" was too.

I think 'Queer' is one of the Q's. The definition I heard for it now was that 'gay' is someone who wants to have a mainstream life with their same-sex partner while 'queer' is someone who considers their sexual identity a form of rebellion.

From the first sentence on the Wikipedia article:

> Queer is an umbrella term for sexual and gender minorities who are not heterosexual or are not cisgender.

Now, some people personally identify as queer instead of lesbian, bi, or gay for all sorts of reasons; but it is the umbrella term.
