Key EU & Belgium Legal Milestones

| 2018 | Belgium | Gender Recognition Act: legal gender and name change on the basis of self-determination, no surgery or sterilization required |

Key Concepts
- Sodomy laws - Laws criminalizing same-sex acts; last US laws struck down 2003
- The Lavender Scare (1940s-1960s) - US government campaign purging gay and lesbian federal employees
- Section 28 (UK, 1988-2003) - Prohibited "promotion of homosexuality"; chilling effect in schools
- Anti-trans legislation - Surge since 2020 in the US targeting healthcare, sports, bathrooms, and curriculum; nearly 600 anti-LGBTQ+ bills in a single 2025 US legislative session (ACLU)
- "LGBT-free zones" - Symbolic declarations by ~100 Polish municipalities (2019 onward) opposing "LGBT ideology"; condemned by the European Parliament in 2020 and challenged through withheld EU funding. Most were rescinded by 2023 under legal and financial pressure
- "Gender ideology" / "anti-gender" movement - A transnational political framing (prominent in Poland, Hungary, Russia, and parts of the US) that casts LGBTQ+ rights, sex education, and gender studies as a threatening "ideology." Used to justify restrictive legislation; opposed by LGBTQ+ and human-rights organizations as a disinformation frame
- SOGI / SOGIESC - "Sexual Orientation and Gender Identity" (and, in the longer form, "Gender Expression and Sex Characteristics"). The standard terminology in international human-rights law and UN bodies for the protected dimensions
- LGBTQ+ asylum - LGBTQ+ people facing persecution may claim refugee status under the 1951 Refugee Convention (membership of a "particular social group"). In practice, claimants are frequently required to "prove" their identity to immigration authorities, sometimes by invasive or stereotype-based standards. The EU bars requiring "tests" of sexual orientation, but credibility assessments remain contested. Recognition, detention conditions, and safe-country rules vary widely by receiving state
Note: Slovakia's two-sexes constitutional amendment passed 26 Sep 2025; Sweden's 2025 gender-recognition law still requires a medical certificate (not full self-ID).
