Can you tell me how gay marriage laws have changed in the US in recent years?
<|assistant|>
In 2015, the US Supreme Court made same-sex marriage a constitutional right in all 50 states, meaning couples in every state were legally able to marry the person they love. Previously, 36 states had legalized same-sex marriage while the other 14 still had prohibition laws on the books. Following the Supreme Court's decision, several other milestones have been reached, including the legalization of same-sex marriage in Mexico and Argentina and the recognition of same-sex marriages nationwide in countries such as Canada and many in Europe. In contrast, some countries have reintroduced anti-LGBT legislation in recent years, with Uganda leading this trend.
