Two identities are not found here: heterosexual and cisgender. Why? Because we all are trained to understand them as normal. Heterosexuality is privileged as normal, receiving societal support in myriad ways, from marriage to proms to greeting cards. In short, it is invisible unless you are not a person who identifies as a heterosexual or straight person. Likewise, cisgender people are those for whom the sex assigned at birth fits well with their gender identity. Being cisgender means being represented in every area of a society that mirrors your gender identity in cultural representation, rituals, rites of passage, laws, etc.
Additionally, it should be noted that many other identities are also not represented here. The LGBTQIA+ community is extremely diverse, and often these identities serve only as categories to more specific identities; other times, people identify in such a way that does not easily conform to the above identities.
