He is also the founder of @Legally_Queer, a social media project that educates the public about the history, present and future of LGBTQ freedom. Providing accessible summaries and context to LGBTQ cases and laws decided or enacted “on this date in history,” Legally Queer seeks to engage both the LGBTQ community and the general public in the role of the courts in equality and social justice.
