Intersectionality theory drove the expansion of identity-based vocabulary.

Evidence

Critical race theory (CRT), particularly scholar Kimberlé Williams Crenshaw’s concept of intersectionality, provided a framework for understanding how overlapping minority identities compound oppression. This theory also influenced the left’s evolving language. Advocates introduced the term BIPOC (Black, Indigenous, and people of color) to reflect the perceived acuity of racial oppression. Similarly, LGBTQ+ expanded its scope to ensure equal visibility for lesbians, bisexuals, transgender individuals, queer people, and other sexualities and gender identities. — W. David Marx, Blank Space, 462
