I don't recall any anti-liberal agenda laws being passed. If anything, there was some protections passed.
Here are some highlights from
https://transequality.org/the-discrimination-administration (that page is much longer than this,
with a lot of it being legal stuff about discrimination on the basis of sex and whether that applies to transgender people):
January 20, 2017: On President Trump’s inauguration day, the adminstration scrubbed all mentions of LGBTQ people from the websites of the White House, Department of State, and Department of Labor.
March 5, 2018: The Department Housing and Urban Development Secretary announced a change to its official mission statement by removing its commitment of inclusive and discrimination-free communities from the statement.
April 11, 2018: The Department of Justice proposed to strip data collection on sexual orientation and gender identity of teens from the National Crime Victimization Survey.
May 11, 2018: The Bureau of Prisons in the Department of Justice adopted an illegal policy of almost entirely housing transgender people in federal prison facilities that match their sex assigned at birth, rolling back existing protections.
March 13, 2019: The Department of Defense laid out its plans for implementing its ban on transgender troops, giving an official implementation date of April 12.
April 12, 2019: The Department of Defense put President Trump’s ban on transgender service members into effect, putting service members at risk of discharge if they come out or are found out to be transgender.
July 3, 2019: The Department of Housing and Urban Development removed requirements that applicants for homelessness funding maintain anti-discrimination policies and demonstrate efforts to serve LGBT people and their families, who are more likely to be homeless.
July 23, 2020: The Department of Housing and Urban Development formally announced the rollback of a previous rule that protected transgender people from discrimination by homeless shelters and other housing services receiving federal funds.
(I had read
this some time ago, so I knew there had been changes under Trump.)
