Terms like "deadname" (the name a trans person no longer uses), "egg" (a trans person who hasn't realized they're trans yet), and the use of they/them singular pronouns originated or were popularized in trans spaces before entering mainstream LGBTQ+ discourse.
The transgender community did not join the LGBTQ+ movement as latecomers; they were founders.
Today, the "T" is not a separate cause. Anti-LGBTQ legislation targeting drag shows, bathroom use, and healthcare access often hits trans and gender-nonconforming people first and hardest.
Supporting the transgender community within LGBTQ+ culture means moving beyond rainbows to real action.
