Additional details and links on some of the terminology:
LGBTQIA2S+ is a shorthand for lesbian, gay, gender non-conforming, genderqueer, genderfluid, bi, trans, queer, intersex, asexual, agender, two-sprit, and others (including non-binary people) who are not straight, cis, and heteronormative. Julia Serrano's trans, gender, sexuality, and activism glossary has definitions for most of terms, and discusses the tensions between ever-growing and always incomplete acronyms and more abstract terms like "gender and sexual minorities".
Misgendering is the act of referring to someone using a gender or pronouns that do not correctly reflect their gender identity. If somebody points out that you've unintentionally misgendered somebody, please edit your post(s) accordingly. Deliberate or targeted misgendering, where there is an intentional refusal to respect an individual's self-identified gender and pronouns, is considered a form of harassment and discrimination.
Deadnaming is referring to a transgender, non-binary, agender, genderqueer, genderfluid, gender non-conforming, two-spirt, or gender-diverse person by a name they used before their gender transition. If somebody points out that you've unintentionally deadnamed somebody, please edit your post(s) accordingly. Deliberate or targeted deadnaming is considered a form of harassment and discrimination.
"conversion therapy", which aims to change an individual’s sexual orientation or gender identity, is a discredited practice that is harmful and disrespectful to the LGBTQ+ community.
Sea-lioninisg a type of trolling or harassment that consists of pursuing people with relentless requests for evidence, often tangential or previously addressed, while maintaining a pretense of civility and sincerity ("I'm just trying to have a debate"), and feigning ignorance of the subject matter
