Queer is the Q in LGBTQ. There’s also the chant “We’re here. We’re queer. Get used to it.” The word is used within the LGBTQ community as a catch-all umbrella term for any gender nonconformity–including LGBT, but also things that don’t quite fit neatly into those categories. Like all reclaimed pejorative terms, the meaning changes significantly depending on the context, and can present outsiders with some anxiety about when it’s okay to use it. For example, it also still gets yelled at LGBTQ-perceived people in a threatening manner (the pejorative usage). So if you’re not sure you’re using the word correctly, it’s probably best to steer clear. But the headline seems fine to me.
LGBTQIA-EIEIO
It took me awhile to realize the EIEIO part was added in sarcastically. It changes so often I probably wouldn’t be surprised if that was the correct term now.
