Just wait until you hear that the US fully repealed all laws penalizing sodomy (which included homosexual intercourse) between two consenting adults in 2003, when the Supreme Court declared that such laws were unconstitutional under the equal protection clause (Lawrence V Texas).

The progress in that regard was fortunately very quick. In 2009, first states started legalizing gay marriage, in 2013 SCOTUS decided that even gay pairs from states that banned gay marriage can receive benefits if they have a valid marriage license from a states that allowed it (US v Windsor), striking down the shameful Defense of Marriage Act, and in 2015, it was at last decided that the constitution protects gay marriage, making it legal in all states (Oberfeller et al V Hodges). In 2020, in an opinion paradoxically written by Neil Gorsuch, a Trump appointee, the court decided that the protection guaranteed by the Civil Rights Act of 1964 applied to LGBTQ folks as well (Bostock V Clayton County).
