He is regarded as the most pro LGBTQ president in US history

President Barack Obama signed Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act into law on October 8, 2009. This Act expanded the 1969 federal hate crime legislation in the United States to encompass offenses motivated by a victim's gender, sexual orientation, gender identity, or disability, whether actual or perceived. Obama signed the Don't Ask, Don't Tell Repeal Act on December 22, 2010. This Act provided a procedure for repealing the "don't ask, don't tell" policy, which prohibited openly homosexual, lesbian, or bisexual people from serving in the military.

As a result, the Act allowed openly gay, lesbian, and bisexual people to serve in the United States armed forces. Furthermore, in 2012, Obama became the first sitting American president to publicly endorse same-sex marriage legalization; and in 2013, he became the first American president in office to call for full equality for gay Americans. Due to these steps, Obama is widely regarded as the most pro LGBTQ president in the history of the United States.
