Purchasing a Pridetocat or Transtocat shirt or tank top from the GitHub Shop supports several LGBTQ organizations, with all proceeds going to the Transgender Law Center, TGI Justice Project, El/La Para TransLatinas, Trans Lifeline, and the Alliance Health Project. These organizations work to empower and support LGBTQ communities through various initiatives, such as advocating for legal and policy changes, promoting self-determination and gender justice, and improving mental health and wellness. The shirts are available until September 30th, and the initiative aims to educate and unite LGBTQ individuals, fostering a future where authentic expression and self-determination are recognized as fundamental rights.
