Non-trans is a descriptive term for any person whose gender identity matches their sex assigned at birth. The term is a shortened form of non-transgender. Non-trans people may be males that were born male or females that were born female. They can have any sexuality.
Non-trans is a synonym for cisgender or its shortened form, cis.
More About Non-Trans
Non-trans may be used in preference to cisgender as it is easily understood, even if you have never heard the term before. Since it contains the word trans, and thus makes transgender the default identity, some proponents of this descriptive term believe it will normalize transgender people and help them gain more mainstream acceptance.
However, some people argue that categorizing people as either trans or non-trans is problematic. They say that lesbian, gay, and bisexual people, even if they are non-trans, have more in common with the transgender community than heteronormative people. They say that grouping these people fails to understand that even lesbian, gay, and bisexual people who align with their sex assigned at birth often struggle with the way they express or feel about their gender, similar to the way trans people do.
Creating a trans and non-trans binary also alienates intersex people, whose sex assigned at birth is not so straightforward. Intersex people may have no sex assigned at birth or a sex assigned at birth that comes only after medical intervention. This means that for intersex people, deciding whether they align with their sex assigned at birth can be a little more complicated. An intersex person who is non-binary can be seen as having a gender identity that aligns with their sex at birth, and therefore could be classed as non-trans.
