An umbrella term for those who do not follow gender stereotypes, or who expand ideas of gender express or gender identity.
GNC does NOT mean non-binary and cisgender people can be GNC as well.
It is important to respect and use the terms people use for themselves, regardless of any prior associations or ideas about those terms. While some parents and allies use the term “gender expansive” (see Gender Expansive), gender non-conforming is the preferred term by the LGBTQ+ community; always use the term preferred by an individual with whom you are interacting.
