I think Brad captures this history well:
After the U.S. Supreme Court legalized gay marriage nationwide in the landmark 2015 decision Obergefell v. Hodges, many believed the fight for gay rights would begin to wind down. Yet that didn’t happen. Instead, the LGBT-advocacy sector simply redirected its available staff, fundraising and rhetoric to other projects. …In a relatively short period of time, the gay-rights movement fused with more radical campus-based gender and identity-politics movements, to become the compound movement now known as “LGBTQ+”—lesbian, gay, bisexual, transgender, “queer” and more. Even many people within the movement now have trouble keeping up with all the new subcategories contained within that plus sign. …
None of these bizarre neologisms have any resonance to those of us who joined the gay-rights movement simply to affirm and protect the basic rights of people to be who they are and love who they choose without stigma or legal sanction. We’ve been forced to watch the simple moral logic of non-discrimination be transformed into a self-parodic alphabet soup of invented identities.
And worth repeating:
