I looked up more on ha, Tulsi was a mess in the 00s
She has, in the past, opposed both civil unions and same-sex marriage. In 2004 she argued against civil unions, saying "To try to act as if there is a difference between 'civil unions' and same-sex marriage is dishonest, cowardly and extremely disrespectful to the people of Hawaii who have already made overwhelmingly clear our position on this issue... As Democrats we should be representing the views of the people, not a small number of homosexual extremists."After her tour of duty in the Middle East supported repeal of the DOMA and became a co-sponsor the Respect for Marriage Act after her election to Congress, as she had promised to do during her campaign. She also asked Hawaii state legislators "to pass legislation that will ensure fair and equal treatment for all of Hawaii's citizens".
During her first Congressional term, Gabbard co-sponsored HR 1755, legislation that prohibited employment discrimination on the basis of actual or perceived sexual orientation or gender identity. She also co-sponsored two bills related to sexual orientation in the military. HR 2839: Restore Honor to Service Members Act gave military discharge review boards the discretion to retroactively grant honorable discharges to former members of the Armed Forces who were discharged because of their sexual orientation. HR 683 Military Spouses Equal Treatment Act provides the same benefits to same-sex military spouses as it does to different-sex spouses. In her second term, Gabbard co-sponsored HR 3185 The Equality Act, which amends the Civil Rights Act of 1964 to include sex, sexual orientation, and gender identity among groups protected from discrimination in public places. She was also an original co-sponsor for HR 197 Respect for Marriage Act, which would repeal the Defense of Marriage Act.
In 2004, Gabbard expressed her opposition to Hawaii undertaking research on LGBT students in Hawaii, arguing that it would be a violation of their privacy and that "many parents would see the study as an indirect attempt by government to encourage young people to question their sexual orientation". At the time, she disputed that Hawaii schools were rampant with anti-gay discrimination.
She publicly supports reproductive choice and LGBT populations, saying that the government should not be the "moral arbiter" in people's lives. While Gabbard's view on LGBT related policy has evolved, in a 2015 interview she indicated her personal beliefs about the matter were unchanged.[125] She credits her tours of duty in the Middle East with triggering her change in views: "It brought me to a deeper understanding of the meaning of freedom in our country. … We cannot afford to walk down that dangerous path of government overstepping its boundaries into the most personal parts of our lives."
Glad she evolved, but against civil unions of all things back in the day

Although, it says her father is strictly anti-LGBT. Katy Perry and her parents teas.
