I don’t know about trans people specifically but he has been a supporter of gay rights for a few decades.
Brooks has long voiced support for the LGBTQ+ community. In 1992, he released “We Shall Be Free,” a song denouncing homophobia, racism, pollution, financial inequality, and religious intolerance. Its lyrics state: “When we’re free to love anyone we choose / When this world’s big enough for all different views / When we all can worship from our own kind of pew / Then we shall be free, yeah.”
Brooks credits his deceased lesbian half-sister Betsy Smittle with developing his views on gay rights and same-sex marriage. In 2000, he performed at the Equality Rights benefit concert for Gay Rights at RFK Stadium in Washington D.C… There, he performed a duet with gay pop star George Michael to Michael’s song, “Freedom ’90.”
