So a tricky thing with LGBT words is they seem to around specificity.

Like people can say gay to mean gay men, gay people, or any kind of queer.

Similarly transgender can mean a gender identity not matching your biological sex, which includes genderfluid; or it can mean specifically a binary trans man/woman.

These aren’t different valid opinions about the label. They are literally just different definitions for the words that depend on context. The words mean all of those things but usually only one in a context.
