A Lesbian is a female who is sexually attracted to females, and queer means anyone who doesn't feel attracted to just one gender. Queer can mean anywhere from transgender to gay, or even asexual.
“Queer” also can connote ways of experiencing or expressing sexuality or gender that deviate from norms, so for example, a gay man whose experience of sexuality deviates from that of most other gay men, anyone who is polyamorous, people who are into kink, and the like. These things alone usually don’t lead to people identifying as queer, but in my experience people who experience more of these deviations are more likely to identify as queer.
Queer is a reclaimed slur, which means several things:
- Many people who might technically qualify as queer, don’t necessarily want to identify that way.
- People can take offense at the word “queer”, especially if it’s used in a context that seems negative.
- The word can have somewhat of a political connotation. It is more likely to connote allegiance to left-wing politics than other words like “gay”, “bi”, or “trans”.
When in doubt, *never* refer to a person as queer unless you are sure the person identifies that way and/or is comfortable being referred to in that way. And always be sure that, when you do use the word, it is in a context that would be interpreted as positive or supportive of queer people.
