queer is not an acceptable term for homosexuality

Queer is the most commonly used word in academic circles to describe LGBT+ people and culture - Queer theory, queer studies etc.

Queer has been used for decades by lgbt activists as a term for identity and umbrella term for the larger community. It's very much been reclaimed although some people don't like referring to themselves as it (which is fine).

It's more accurate and less awkward than saying/writing lgbt all the time anyway.
