There are several synonyms for the term "straight people." The most common synonym is "heterosexuals," which refers to individuals who are exclusively attracted to individuals of the opposite sex. Other synonyms include "cisgender," which refers to individuals whose gender identity matches the sex they were assigned at birth, and "non-LGBTQ+," which refers to individuals who are not part of the lesbian, gay, bisexual, transgender, queer, or questioning community. While these terms may be useful in some contexts, it's important to remember that language evolves and can be divisive, so it's important to use words that respect and include all individuals regardless of their sexual orientation or gender identity.
