However, as opposition grew, largely on partisan lines, the future of legalized same-sex marriage was less certain.
And legalizing same-sex marriage was not a complete victory: Heterosexual couples are still afforded greater rights with regard to adoption, and transnational same-sex couples cannot marry in Taiwan unless both countries recognize same-sex marriage.
However, as seen in South Africa, which legalized same-sex marriage in 2006, and Ecuador, which legalized same-sex marriage in 2019, public opinion does not always improve after legalization.
So far, messaging from supporters of same-sex marriage has had far more limited media coverage than their opponents.
